I've gone over all my ADE (program) settings and can't seem to find that particular setting. Could you please point me in the correct direction? Attached is what I have now.
It's right there in your screenshot, the "separate airport and object bgl files".
Which I guess should be disabled in this case but if doesn't work, we really can't help you here. The scenery works correctly as supplied, explaining how to modify it with ADE is really outside the scope of this support forum, since our responsibility it's ensuring the scenery work as it is, and it surely does.
