The problem was caused because:
- The name of the scenery AFCAD changed from the previous version, from AF2_LPMA.BGL to LPMA_AFX_OP02.BGL, so the previous GSX customization, which is loaded depending on the the name of the active AFCAD, wasn't loaded.
- The elevation in the AFCAD changed from 50.5 meters in the old version, to 43.60 in the new one. Of course, the real elevation is neither 43.60 nor 50.5 but it's sloped from 44 meters on one end to 58 meters to the other one, but the sim doesn't really support sloped runways, the scenery designers likely opted for a different "in the middle value".
This has been fixed in the latest FSDT Live Update.
