Staircase shows sky

[LMA1324]

Hello!

How can I make sure that the staircase does not show the sky but the level above. The "show ceiling" box is checked on both levels.

You can see what I mean here https://ibb.co/vZ2DPTk

The problem lies with the staircase. I did not misfit the room and walls.


Thank you!
