Dino stand expert? (Car Mechanic Simulator 2018)

Can't send a car on a dyno stand in the expert mode. Writes the place is already occupied.
Went again to 30+ level - the same crap! Litsuha.

On normal difficulty it works.

And even the expert - it is not clear how to customise garage expert ? and no store boxes and accordingly, it is impossible to set a checkpoint.

The developer put a clear explanation of the difference between the EA mod and the normal game on the level of availability of different chips.
