Inconsistent Fascia Heights on Hip Walls Within Same Room

[DefinedDesign]

Here is the latest version of the plan

This version shows how the roof planes over the connecting room should be (even though, for reasons I can’t figure out, the two planes do not have the same fascia height).

 

I was able to add an attic wall to the back part of the house where there was a hole in the wall, and that corrected the issue there. However, adding an attic wall over the stairs did not solve the problem in that area like it did on the back of the house.

 

If anyone has ideas on why the fascia heights are still different, or why the attic wall over the stairs isn’t resolving the gap like it did in the other location, I’d be so grateful for your input.
