I'm sorry, but it's still not very clear, not because how you took the screenshot, but because of the angle.
I think I'm seeing double scenery but, with that view is difficult to tell.
However, there are several things that are VERY wrong with your picture, apart the roofs, you have an frame rate so low, which clearly indicates someting is wrong, and it might be due to a double scenery.
Surely, the problem is not caused by FSDT KFJK, but by another scenery in conflict. If you have an addon AI Traffic Package, most probably you have an AFCAD file which was designed for the default scenery, that you need to remove if you are using an addon airport.
How to do this: you need to ask to support of the AI traffic package you are using, because each one uses different names and locations.
However, it's clearly a problem caused by another scenery. There are free utilities, like the FSX Airport scanner, that will try to search for double sceneries but, if you don't know what you are doing, it's best to ask to those that made that scenery.
