Minor issue but when I order catering for the PMDG 747-400F I get two large catering trucks and a request to open doors that are not present.
Please indicate precisely which doors you are requested and especially how they are named.
The default configuration that comes with GSX for the PMDG 747-400F expects two catering doors, named "R Entry 1" and "R Entry 5", which are associated to the 7X7XCabinDoor1R and 7X7XCabinDoor5R custom XML variables.
I checked the .MDL files themselves, and both door exists in the model.
