In the coutl log it says that it has loaded AFCAD .... scenery\world\scenery\AFX_MDDE_ALT.BGL When checking thar register that particular AFX file is'nt there.
It's not possible that GSX would load a file that doesn't exist. If it tried to do that, it would give you some kind of error, like trying to access a file that doesn't exist.
So, if you haven't seen such error, that file is surely there.
From the name, it seems the file is an altitude correction AFCAD, so it shouldn't contain any parkings but, if GSX has chosen it, it means there are parkings in it.
The weird name seems to be a fake ICAO ( EDDM spelled backward ) and, as I've said in my previous reply, if an airport use auxiliary AFCADs with fake ICAO names to represent helipads, for example, they must by excluded from GSX using the
airport_visibility command, explained in the
GSX manual at page 24.
