I think I have answered this question for myself. When looking at ASCE 7-22 Figure 30.4-1 Note 4 they indicate +GCp values use qz and -GCp values use qh. I think +GCp are representing windward walls and -GCp are representing side and leeward walls. I was incorrectly considering both +GCp and -GCp values for Windward and Leeward/Side walls.
