Trimmed to roof walls outlines are showing in floor below

[Matratzis]

Hi,

when I trim my walls to the roof the outlines of the walls are showing in the floor below. 

However they aren't even connected with the floor below. 

 

I tried to change the walls settings as to only show in the assigned floor and played with the floor plan cut plain settings.

nothing seems to work and it shouldn't even be possible that they show in this floor.

Thanks for helping

Okay i got it. 

looking for the error for like two hours and just after i posted this i found it lol.

The roof, the walls are connected to is going in the floor below. I change the floor plan settings there and everything works.
