Hello! I just updated to HD Pro 2025 and when I create a shed dormer, there is a white box that appears over it. I have made sure that all of my roof lines are connected, there are no intersecting walls in the attic space and the "ceiling break lines" are turned off. The plan view shows the roof lines of the box, but I can't select them. Any help to resolve this issue is greatly appreciated. Thanks!
