Remove space between Oracle APEX page items

I have created two APEX checkbox items on top of each other, one being the checkbox selections (complete, incomplete) and one being a select all option above it (with associated JavaScript to enable the select all functionality). Everything works great, but I am trying to remove the white space in between the page items.

The checkbox item with the selections has no label because the Select All item has the heading for both items to be treated as "one item" to the user. I think the template might still be accounting for the label padding, but I'm not sure.

Does anyone know a solution in order to remove the white space (I'd be find with a small amount of white space but right now it is very large and doesn't look visually appealing.

Open up the template options, and set the desired margin attributes to 'None'
