where is says "add a tab object to the screen", so I've added a tab container, and it doesn't seem to work. I've been able to add a Units Data view object and a Sales Data view object, but the tab container doesn't seem to interact with them at all. I've tried dragging every which way within it, but no reaction from the tab container. When I go to the tab itself, under Tab settings its blank like it doesn't recognize any object in it.
