[SOLVED] JavaFX 8 TableView not populating from ObservableList (no FXML)

I believe I've searched all of the similar questions, but still am not seeing my issue anywhere. I am populating an ObservableList from a database which is succeeding per my Console output. I have a multiple controller setup for a school project to create a scheduler app. I have a root controller which functions as the borderPane, two functional controllers for Appointments and Customers which are all Singleton, and a shared DataView controller which is not to allow each view to instantiate its' own DataView. I've implemented toString on each of the controllers to spit out what the values and/or object Ids of each element are and everything seems to line up. I can't for the life of me figure out why the ListView or TableView aren't outputting the bound data. Here's the view data that I'm trying to bind to both ListView and TableView

public class AppointmentView implements IAppointmentView {
    private final ZonedDateTime createdDate;
    private final String createdBy;
    // Interface needs these components
    private ReadOnlyStringProperty title;
    private ReadOnlyStringProperty description;
    private ReadOnlyStringProperty location;
    private ReadOnlyStringProperty contact;
    private ReadOnlyStringProperty url;
    private ReadOnlyStringProperty customerName;
    private ReadOnlyObjectProperty<ZonedDateTime> start;
    private ReadOnlyObjectProperty<ZonedDateTime> end;
    private ReadOnlyProperty<ZonedDateTime> lastUpdated;

    /***

    public AppointmentView(String title, String description, String location, String contact, String url, String customerName, Timestamp start, Timestamp end, Timestamp createDate, String createdBy, Timestamp lastUpdate) {
        this.title = new SimpleStringProperty(title);
        this.description = new SimpleStringProperty(description);
        this.location = new SimpleStringProperty(location);
        this.contact = new SimpleStringProperty(contact);

As mentioned, I put in a few toString calls and implementations and I keep seeing the objects in DataViewController per this:

listView=[AppointmentView{createdDate=2017-09-02T00:00-07:00[America/Los_Angeles], createdBy='test1', titleProperty=StringProperty [value: Meet with Amari], descriptionProperty=StringProperty [value: Meeting WR of the Raiders], locationProperty=StringProperty [value: Raiders HQ, Alameda], contactProperty=StringProperty [value: Jack DelRio], urlProperty=StringProperty [value: raiders.com], customerName=StringProperty [value: Amari Cooper], startProperty=ObjectProperty [value: 2017-09-04T16:00-07:00[America/Los_Angeles]], endProperty=ObjectProperty [value: 2017-09-04T16:15-07:00[America/Los_Angeles]], lastUpdated=ObjectProperty [value: 2017-09-02T23:07-07:00[America/Los_Angeles]]}, AppointmentView{createdDate=2017-09-02T00:00-07:00[America/Los_Angeles], createdBy='test1', titleProperty=StringProperty [value: Meet with Amari], descriptionProperty=StringProperty [value: Meeting WR of the Raiders], locationProperty=StringProperty [value: Raiders HQ, Alameda], contactProperty=StringProperty [value: Jack DelRio], urlProperty=StringProperty [value: raiders.com], customerName=StringProperty [value: Amari Cooper], startProperty=ObjectProperty [value: 2017-09-04T16:00-07:00[America/Los_Angeles]], endProperty=ObjectProperty [value: 2017-09-04T16:15-07:00[America/Los_Angeles]], lastUpdated=ObjectProperty [value: 2017-09-02T23:07-07:00[America/Los_Angeles]]}], 
tableView=[javafx.scene.control.TableColumn@6167e82, javafx.scene.control.TableColumn@50658769, javafx.scene.control.TableColumn@f65aae1, javafx.scene.control.TableColumn@2d5ab3ab, javafx.scene.control.TableColumn@180d2aec, javafx.scene.control.TableColumn@64afb84b, javafx.scene.control.TableColumn@463f349d, javafx.scene.control.TableColumn@3e80101a, javafx.scene.control.TableColumn@4fab076c, javafx.scene.control.TableColumn@565f8332, javafx.scene.control.TableColumn@697bdeb8]

And here's the MainApp method that's calling it:

private void initLayout() {
//        rootPane = new BorderPane();



    appointmentViewController = AppointmentViewController.getInstance();
    appointmentView = appointmentViewController.apAppointmentView;
    appointmentViewController.setMainApp(this);

    dataViewController = appointmentViewController.getDataViewController();
    dataView = dataViewController.tabPane;
    dataViewController.setMainApp(this);

    customerViewController = CustomerViewController.getInstance();
    customerView = customerViewController.apCustomerView;
    customerViewController.setMainApp(this);

    appViewController = AppViewController.getInstance();
    appView = appViewController.getBorderPane();
    appViewController.setMainApp(this);

    appViewController.setDataViewController(appointmentViewController.getDataViewController());

    System.out.println(this.dataViewController);
    System.out.println(this.dataView);
    System.out.println(appointmentViewController.toString());
    System.out.println(customerViewController.toString());
    System.out.println(appViewController.toString());

    rootPane = (BorderPane) appView;


    scene = new Scene(rootPane);
    scene.getStylesheets().add("/styles/Styles.css");

    primaryStage.setScene(scene);
    primaryStage.show();
}

I've setup the CellValueFactories,etc. What am I missing here?

This is how the UI is shown:
