I am wondering if anyone else has this issue. I am running P3D V4. When I am at any gate of any airport and wanting to modify the GSX 2 ground equipment/jetway, as soon as I select the modify button the PMDG 737 is slewed straight back, far away from the gate. This happens only with the PMDG 737 (600,700,800, & 900). All other planes, including PMDG 747 and 777, stay at their gate positions and allow modifications to ground equipment.
