In the attached pictures it will look like I have a jumble of overlapping flex grids and text. The "FlexGrid-700" is not there, just it's ghost...
Any ideas on how to get this to stop?


Actually it should GN. The ability to hide objects is a standard/normal feature. It is used to hide objects across viewports - for example if you wanted a "tap to phone" icon in mobile/cell phone views.But this shouldn't be happening so I think it deserves checking into still.
