Ok, tried with the Follow Mode on and no difference...
Well, that surely was an issue, since with follow disabled, it would have happened for sure.
the Parking and Parking system editors work as expected. Also if I press F1/F4 for next/prev object the gui comes up again at the same parking spot.
Alright, this is more clear and yes, I can reproduce it, so it will be surely fixed.
Note that, the camera banking with 7/9 can't be fixed unless you disable those key from the camera view, because there's no way in the MSFS SDK ( it was always possible since FSX ) to momentarily prevent a key to reach the sim.
