Some AFCAD data not showing in FS9

I have just completed a scenery file & have added AFCAD & some AI. When I use the Create Flight box in FS9, all the runways & parking positions show OK.But when I use the GPS or Maps, the written airport data only shows one runway. i.e. It shows rwy 34 but not 16. Also the graphic image on the GPS shows a purple circle with a small bar at the N,S,E & W positions, not the filled in circle with the runway direction showing as I expected.Any ideas why this has occurred or how it can be corrected?Peter
