generate wind load using staad pro as ASCE

Dear Expert,

I have one question when applying wind load according to ASCE 7-10 using automatic staad pro wind generator on steel hangar ,

first, i notice that the force that acting on  roof in wind ward direction, didn't perpendicular on the frame rafter as ASCE 7-10 figure 27.4-1 (refer to snap below)

2-the wind side ward didn't appear even i identify this case in staad definition
