KLGA only recognized as FLUSHING airport in AFCAD

I have DRZ extract KLGA, but GSX is not recognizing as such when I go into the setting airport. It reads as FLUSHING. How do I modify this so it recognizes my addon scenery correctly. Where do I find AFCAD on my computer to do this if possible. The airport looks correct in FSX, and in the files.

Of course, that thread is related to another airport, but it's the same: when you have two airport too close to each other, or even one inside another, you can use that feature to exclude one, so GSX will recognize the main one.

Thanks for pointing out that thread. Success after figuring the ICAO for Flushing is just FLU.
