A350 EFB Load with GSX not correct

[mseder]

Using the "Load with GSX" option in EFB LOADSHEET do not work/work properly.
I'm also using the Enable GSX control in the EFB GROUND

It starts loading the fuel but then it do not continues or waits too long.
If I handle the GSX manually I start with 1 Fuel and directly after that 2 Catering Service and immediately after that 3 Boarding

This should be the procedure that Load with GSX shoul initiate.
