Hey everyone, I really need some help. I just started learning and using Chief Architect 2 weeks ago, and the learning curve is pretty steep but all was going well. Now however all of a sudden, there are massive gaps between my floors!! Its like there are no coverings for the ceilings/floors... the weirdest part is that it only happens under glass walls. I attached images and also the plan.
If you know how to solve this please help!! Its been driving me nuts.
