Elements under a UiListLayout will render a bug when having a child added while frame is not visible
In the top photo, that bottom text was added to the frame when the frame was not visible, and when returning it to visible it came to be flatten.
Bottom photo show it correcting itself when a new child is added to the parent frame.
The flatten frame will also fix itself if any of its children are selected via Selection in studio.

Thanks for the fast reply on this! I found a temporary fix for this to when I’m switching back to the frame, to set all frames visible to false and then right back to true.
