Default aircraft loading into payware scenery

Question

I recently bought the Seattle airports do scenery from the x plane. .Org store, but when I load up the scenery I get a lot of the default aircraft loading in with the ones that come with the scenery. I have tried everything to try and get them to not load in, but so far have had no success. I was wondering if this is a problem with x plane or the scenery. If it is a problem with x plane, is there a solution? 

Thanks

I thinks it's a problem in the custom scenery. I wonder why you bought the Seattle airports when they are included even in the demo.
