A350 GSX bug

[Hi58]

When I am pushing back using GSX when the plane is lifted off the ground the planes starts moving forward on its own?? And then I select to start the pushback. The tug spawns by my plane and when they are releasing the tug my planes starts moving forward again

I tried more stuff and the bug is specifically in the A350-900 it works fine with the -1000
