I have also confirmed this issue.
The first photo shows the VDGS not running.
The second photo is in operation.
The third photo is stopped at the position specified by the airplane.
We have confirmed that it is operating normally at the airports created by FSDT (KORD, KLAX, KJFK).
In addition, the position of the customized VDGS is abnormal at FlightBeam's KSFO and aerosoft's airports (EDDF, EGLL).
