I was talking to a "Friend" of mine who created the objects a long time ago (ArchiCAD 5.0 or so)....
The JACK TRUSS option should have been corrected to say HIP.. where using this FEATURE, you could type in the normal truss pitch, click ON for HIP and it would adjust the pitch to the correct HIP PITCH required for that roofs normal pitch...
Anyway, I am hoping the switching OFF the JACK (hip) feature would correct your problem. I think the part defaults to ON...
