I keep getting the error, "Unimplemented substep definition" in IntelliJ with Cucumber?

I have already:

• Downloaded the Cucumber Java, Gherkin plugin
• I already have the steps and features directories:

My directory structure looks like this:

- test
    - java
        - features
            - featureSet1
                - oneFeature.feature
                - anotherFeature.feature
            - featuresSet2
                - twoFeature.feature
            - CucumberTests.java
        - steps
                - step1.java
                - step2.java

Under the features folder, I have a file called, CucumberTests.java. I'm able to run the tests via mvn test but the red error marks reallllly annoy me.

I have these tags in CucumberTest.java, which is supposed to run the tests:

@RunWith(Cucumber.class)
@CucumberOptions(plugin = { "pretty", "html:target/surefire-
    reports/cucumber", "json:target/surefire-
    reports/cucumberOriginal.json"},
             features = {"src/test/java/features/featuresSet1",
                         "src/test/java/features/featuresSet2",
                         },
             tags = {"~@ignore"},
             glue = {"steps"})

The issue is from Substeps IntelliJ Plugin that IntelliJ suggests you install when it locates a .feature file inside your project.

Just ignore this extension when it pops up or uninstall if you already have it.

Cucumber for Java and Gherkin should be enough.
