FSX/GSX parking facilty issue

[vivalasvegas]

Started FSX and chose Gate C30 in Ray Smith's KORD scenery. Loaded aircraft and position at jetway was perfect!  Started GSX (CTRL/F12) and a box came up asking me to select a parking facility.  Strange!  I chose C30 of course. Half of my aircraft was now located inside the terminal . Please help!  How can I fix this issue? 

Thanks!

First, check to make sure GSX is using the correct AFCAD. If it is, just use GSX to customize the parking position.
