You haven't attached any log, you attached the .ini file that enables logging, which is not helpful at all.
Looking at your screenshot, the passengers being in the air is not really the problem, and might be a result of the other more serious problems. I see what looks like two set of ground vehicles, as if GSX couldn't remove the default vehicles when the parking was selected, which is something it normally always do but, if if didn't, it might indicate some scenery conflict, like a problem with parking positions, or the wrong GSX profile loaded, or a combination of both.
Scenery conflicts are easily noticed before flight by looking at the world map and see if you have any overlapped parking spots. If yes, the most common cause of this, is having forgotten to disable the GSX Jetway replacement file after installing a new scenery, which is something you should always do, since those files are only supposed to be used with default airports.
