Orbx SAK presents 5Z7/Kasitsna just as a very simple sandy dirtstrip on the beach without any buildings. (what you see in your screenshot)
The additional scenery in your picture comes from any other added software which does not fit to Orbx SAK.
Do you have FSG_ATAP_US_SEAK from FSGenesis installed?
If yes, you must deactivate "5Z7_ADEX_FSG_CVX.bgl
