This is not a problem or a bug or an issue, instead is the result of a needed change to the way GSX position the airplane when NO STOP POSITION IS SET, that is the default placement.
Before the update ( again, when NO custom Stop position is set ) GSX placed the airplane center in the middle of the parking, which resulted in airplanes parking too far behind, and this was more and more noticeable, the bigger the parking radius, and this lead to the discussion in this thread:
https://www.fsdreamteam.com/forum/index.php/topic,28059.0.htmlFollowing all the feedback on that thread, this update moved the default parking position 1/3 of the parking radius ahead, which seems to result in a way closer position compared to the one used by the simulator itself.
Again, this is just the bare position when no customization is made.
The proper and more realistic way, is to customize the STOP position, which will result in the airplane preferred exit always ending up in the same position regardless of the airplane type, resulting in the front gear being in different places, which will improve resolution of the jetway, which is the main reason why in real life there are different stop positions to begin with.
