You realize that the plateau issue is present in every mesh, correct? Due to the airport elevation not being the same as the areas right outside of the airport boundary.

After I bought the software I determined that on my own, but some parts of the FSG website led me to believe that they had fixed the issue in their meshes, and would correct any plateaus that they missed. Even if it is a problem for all meshes, it still does not excuse the complete lack of support, even to tell me that it cannot/will not be fixed.
