GSX suggest a gate only based on the parking radius, but he cannot possibly know that jetway would break apart when used on the 2nd door.
However, the *current* version of GSX will guide the plane to be parked further ahead, if the GSX airplane configuration lists the 2nd door as a preferred exit, so this shouldn't result in the jetway breaking away.
- Are you using the latest GSX ?
- Is your airplane configured in GSX to have the preferred exit on door 2 ?
- Have you parked following the GSX indications ?
This, of course, relates only to your own airplane. AI planes cannot be fixed by acting on GSX, which doesn't control them in any way
