Can't reproduce that. I tried it right now at an airport I know ( FSDT Zurich ), got the normal menu with the correct operators for Zurich ( Dnata, Swissport ), choose Swissport and got all Swissport vehicles.
And since the scenery comes with lots of VGDS in the profile, I checked and they are positioned correctly and are working.
There's nothing in the 3.0.8 update could possibly have affected this.
