FSNav weirdness with FS2004 Flightplan export?

I have noticed recently that when exporting a flightplan from FSNav to FS2004 the drop-down list of parking areas shows the "Stock" airports parking...not the addon AF2 parking. This doesn't happen on every airport I've added (and I have a bunch), just on a few I've noticed, so far. KMIA is one. I have Fly-Tampa KMIA installed and all it's parking shows up on the FSNav Map view perfectly. Once I create and save a flightplan, however, and try to export it to FS(, the FSNav drop=down menu, to select a parking spot, shows only the "stock" KMIA parking list. I have also had some..."bleedthrough" of Stock and Moded airports which results in a weird hybrid of both being shown in the FSNav map...with double listings of spots and both sets showing up on the map. I may have solved this one by moving my "Addon Scenery" folder to the top of the scenery order. This is where I store all my AF2 files. Time will tell but it did NOT solve the Export problem I spoke of above. Any ideas? Vic
