Unable to add data to models in Live Preview #13498

Bug Description

Models appear to have an editor UI in the simulation menu, but the menu doesn't seem to function. There is what looks like a plus button but its lodged in the window controls and isn't clickable. Video Attached.

Product Impact

Not a massive issue just really annoying. Having to go into my app and use real data is a bit of a pain for rapid prototyping.
