Thank you for your answer! It helped me out.
But now i came across of another problem.
Problem is with crowns. I found a thread about this problem but there I could not found a proper answer.
When I choose crown layout for example 20 then everything is okay:

But when I want to remove crown and keep the molding like that, this will happen with base and chair:

Also when I use different crown layout which does not extend as much from the wall as layout 20 then the problem occurs as well:

I will be very thankful if you could help me figure out this problem.
I also downloaded hotfixes but it stayed the same.
