I've tried the default PANC now, and everything works normally, I can see several terminals listed, A, B, C, G, N, R plus many Parkings (more than 11), and went to a random gate, all works and Alaskan Airlines is handling the airport.
Check if you have another AFCAD in conflict: go to a parking that works, and select the "Customize this parking position" option from the GSX menu. Even if you don't really customize anything, it will say which AFCAD GSX is taking informations from.
