If your using the "Dot" control where your pointing the mouse cursor on the dot to use the function then it will not update the state for that function which pretty much render the whole feature useless after the 1th click.
Using the "UserActions" control will however update the state and make it function again.

This issue seems to be affecting only these functions so far (on claas tractor)
- Right door
- Front hydraulics
-Tow pin
- Steering console height
- Steering console rotation
- Start engine

Working are these
- Left door
- Rear window
- Wiper
