Hi all,

I created a project of 4 floors, the first was supposed to be a basement. Previously, it was not possible to create a basement level. Now it has appeared, and I would like to delete the first level, which is now empty for me. I removed the floor, walls. The level looks empty, but the level itself is not deleted and my house is hanging in the air. I can delete the fourth level, a trash icon appears next to it, but the previous three levels do not have such an icon. What to do???
