Don't post XML code in the message, both because it's too long to read, and also because it can be altered by the forum software. ZIP it and attach to a file. And, without the related AFCAD, I can't say if the XML is correct or not.
Also, please clarify what do you mean with "GSX will not use jetways". Do you see those gates listed in GSX with a "/JS" ? If yes, it means GSX has recognized them correctly.
