ROFL. Found the problem, its this part
[fltsim.X]
and
[fltsim.X+1]
If you only have the default EVA Air 77W, that should be under [fltsim.0]
So rename the two Air France ones to
[fltsim.X] ----> [fltsim.1]
[fltsim.X+1] ----> [fltsim.2]
It's all chronological mate, just follows a standard ascending numerical order, it's the same with EVERY SINGLE FS aircraft.cfg and their repaints, because it basically just separates and orders each repaint so the sim can recognise and identify them separately.
Should fix the problem, very mandatory mistake there, this info is all in his readme, next time, I suggest you read it, it'll save you going to the hassle of having to ask here, it's a simple 5 second fix!
Hope that helped!
