The issue is, the vehicles are positioned more precisely than before, which means that some heights will need to be adjusted and, the 737 fwd cargo door it's just barely over the threshold of the minimum height the baggage loader can reach.
If the a vehicle can't reach a door, it will not be displayed so, you will only need to open the Aircraft configuration editor and raise the door just a bit to be over the threshold to accept the loader, a few centimeters more should be enough.
However, I suggest wait a bit if you don't want to edit doors, because we are working on a way to be backward compatible with the existing airplane database.
