No front baggage loader with deboarding

[VolkerfromGermany]

Hello !
If i choose "Boarding" the two baggage loaders connect to the Plane (BAe 146 JustFlight) and baggage loading is starting.
If i choose "Deboarding" only the rear baggage loader connects to the plane, the front baggage loader does not move. Deboarding is also not completing when the baggage loader not connects...
If i choose "reset position" and choose boarding again, the both baggage loaders are connecting properly.

Any ideas?

EDIT :

Now, after one day and reboots at another airport "deboarding" worked correctly...
I dont know why... will observe this
