A mystery to me.
If I adjust your 'Test' schedule I can see there are walls, columns and doors.
All of these are locked and invisible for some reason.
When I schedule the min and max heights of the walls I see the min height is zero, which implies to me that something is cutting it (SEO or a trim to roof?) to a zero height making them invisible in 3D.
But they should still be selectable.
