It would have been better if you included coordinates in your screenshots. However, as I've said, we haven't modeled anything in 3d outside the airport perimeter, while you are using the term "areas covered by this software", so it seems you think the area is larger than the airport perimeter, but it's not.
I don't recognize the photorealistic background in your screenshot (again, it was more difficult by the lack of coordinates), so it seems what you are seeing is a 3rd photorealistic scenery that extends more than KIAH airport perimeter, and THAT one is missing autogen.
