Wall intersections don't work when reversing the layers

Here I have a condition where the intersection is fine:

But if I reverse the layers in the Layer Style, it’s no longer fine:

How can I fix this issue?

I see that there is a solution to ‘flip’ the walls: When I create a wall with more than 1 component... which component is inside and which is outside? - VisualARQ

However, I am wondering why the intersection works in one situation but not in another, when the overall composition of the wall is the same?

Hi @andreaw,

Please, could you send me a file with both cases? I will test it to figure it out.
