Please read my following comment very carful again:
Remember MSFS can currently handle only one jetway. To which door the jetway will be connected is defined in the plane settings. For the Aerosoft A330 this is the door 2L according to RL when only one jetway at a gate is available and GSX uses the same MSFS function to connect a jetway. This only works in MSFS and with GSX if the plane has stopped at the right position. If the AFCAD file is not correct ,the jetway will try to connect to 1L or fails to move at all. But in GSX you have the opportunity to modify the stop-position so that always the jetway will always be connected to door 2L.
GSX connects according to the plane settings and this is the 2L door, but only ,if the stop position ir correctly defined in the AFCAD file of the airport/gate. Otherwise it will connect to the 1L door or even not move at all. But if you are using GSX you can define the stop position for GSX youself (for the plane and the gate) and then GSX will connect also to the 2L door.
