As already explained in all the other threads about this, the problem has been fixed a while ago and, as you can see from that thread, most users that use to have it, reported it to be fixed.
If it's not fixed for you, please indicate ALL the following:
- The precise, exact, sequence of operation you chose in GSX.
- The scenery used. If it's not default, indicate the scenery. If you customized it, indicate how.
- The gate used
- The airplane used. If it's not supported by GSX, or has been customized, indicate how.
- Clarify if the issue happens only on arrival.
