The parts you are missing are not coming from our scenery, they are part of the default scenery. In fact, the only thing that looks correct in your screenshots (apart for the blurry textures, which are caused by not using the Anisotropic filter option on your video card setting), it's the airport itself so, it's sure it's not a problem of the scenery.
It seems that your default scenery is not working correctly, all the coastlines are wrong, but we don't touch, change or modify anything on that, our scenery ends with the airport perimeter.
