Solver: yes I tried reversing wall again; same result, it just put the sheet rock finish on all of the upper wall. Lower wall is sheet rock both sides anyway.
Alaskan-son: In materials it only list the pony wall, which is the lower wall, so both sides are sheet rock. Keep in mind that part of the upper wall does display correctly as an exterior finish. The right two thirds of the area is correct, and the left one third is not.
