Choose an airport problem

[nf22a]

every time i choose a different country/region in FS9, the cities and airports don't change to match the country/region or the state/province that i chose next. For example, i had chosen Canada as the country/region, Ontario as the state/province, Ft. Severn as the city, and the airport at Ft. Severn, but when i had switched to the United States region, the airport stayed at Ft. Severn, Ontario, Canada. i would really like a solution to this problem because it is really annoying me.

Every time you narrow down the selection, you have to "clear all fliters" (the clickable button that says as much), before going back up the logical ladder.

If you narrow it down to say...  USA/Ohio/Cleveland, and then try to go back up to Canada.. the Ohio and Cleveland filters are still set..
