Umberto despite FSDT Update the problem remains.
Your problem now doesn't have anything to do with the update, which was required ONLY to fix a previous bug in the airport_visibility_xxxx command that prevented to exclude ICAO airports with numbers, which was the case for the Z41, so this should be fixed, if you have excluded Z41.
But now you have another problem, the OrbX FTX NA on a higher layer priority than Aerosoft PANC, so GSX is correctly reading that AFCAD, instead of the OrbX one, because it's on an higher layer.
The general rule to avoid conflicts, it's always being sure that airports are on top of everything else.
If else fails, just remove the OrbX AFCAD (when the sim is NOT running!!), and choose the "Restart and rebuild airport cache" from the Couatl menu on the next startup.
