I can only confirm the problem is fixed, which is confirmed by your 2nd screenshot, that shows the marshaller on a ladder. However, its position is too far back, which means the fix for the marshaller distance that is INCLUDED in the latest update is not being read.
I see what the problem is: JFK needs an update too, because it comes with a GSX customization file, and a GSX customization file will always take precedence over the GSX internal configuration, so that file still has the maximum marshaller distance set to 25, so that would need to be changed too.
The customization changes YOU make, will take precedence over any customization made by us (either in the GSX internal code, or in the GSX custom file we supply with JFK V2) so, since I don't think it would make any sense for you re-download the whole JFK installer JUST to apply that small fix yourself, it's easier if you just open the GSX, and set the maximum marshaller distance to 16, which will surely fix the issue, that's why it was my first proposed solution, because it would have worked even without installing any updates.
