Why is Subtraction Geometry Not Making Door?

Hello. I am trying to make a new door (like I had many times over with no problems) using Geometry Boxes. One is for the wall and the other for the door. Now when I adjust the box for the door and set it to subtraction, why is it no longer making the space for the door like it once has many time before? I can not seem to make a door or window any more since I upgraded to UE4.18. Any idea what I may be doing wrong now or has things changed? I am stumped on this one. Here is a screenshot of the subtracted box placed inside the wall set on subtraction. Where the hole go for the door?

I think it’s about the order of brushes that are created, cutting the object and pasting it in the same place worked out for me :).

highlight/select the subtract brush and order it to last
