GSX Detatches Desired Jetways From PMDG 747 at KLAX When Requesting Boarding

[Speedbird ATC]

When I try to board at a three jetway stand at KLAX, GSX forcibly detaches the correct jetways from the PMDG 747, and forces me to use the A380 jetway at the stand. (This is stand 131 but others have the same issue) The jetway glitches through others and overall looks really ugly. How do I change this behavior?

You parked at the 2nd position, is the airplane configured with exit 2 as the preferred exit ?
