American Trucks Groundservice at LOWS Salzburg Austria - Wrong cars for Ground Service with GSX

[MichaelBGL]

Hello ,

I use GSX with the last Update and also the Tool “Remove Ground Services in all Airports”.
But in LOWS Austria Airport from RDPresets there are American Style Trucks and SUVs at the Parking Positions, as you can see here .

Where they come from . As i know the Remove Ground Service Tool should delete them or not ?
Or are this Ground Services a Part from the Scenery himself ?
When i start Boarding with GSX the the original Salzburg Stairs , etc are there .

Thanks
Michael
