Wall interferes with windows

[vivifliouka]

Hello everyone!
I wanted to ask you if you know why this is happening 

I install my windows on a project that was created with an older version of archicad and the wall is still visible behind the windows, the new wall the one I drew up is just fine and although I use ctrl and alt ctrl to copy settings it still is like this. The wall up is new the other is from the older version.

Thank you in advance

Operating system used: Windows 10

Are there 2 old walls in the same location?

i.e. the window is placing in one, but the other wall is still showing.

Check your Renovation Filter. Looks similar to when you have No Filters Applied with a New window in an Existing wall.
