I can only confirm my previous posts, your log still shows the same thing: the airplane exited from the airport as soon you tried to customize the airport. We can probably remove the error itself, but that won't solve the real problem, which is the airplane slewing away so far that even exited from the airport.
You must still have some unused controlled axis still assigned to Slew mode, that's the only possible reason why entering the editor ( which activates Slew ), could result in the airplane exiting from the airport.
