Add Child to Uniform Grid not showing on a tab switcher?

I am just getting started in ue4 and can’t get this test journal I am working on to show a generated list of child widgets on a specific page. Any tips on how to get it working or what I am doing wrong will be much appreciated.

As you can see in the screenshot below nothing is popping up, could it be because I am using a widget switcher and it would allow extra childs on the widget it is switching to?
