I can't move my ceiling up without it creating a new one. I somehow moved my ceiling on the left up but i selected it while the whole thing was blue see through but i cant do it for the other ones since it only gives me a blue outline. I try to put the level up to 'upper floor' where the roof on the left is but then it creates a new ceiling and the other one is still there
how i want it


then it creates a new one
