PlayStation Scenario Planner: Red Light At Dessau Platform 3

Dessau platform 3 in a custom scenario with the Db Br 101:
Today I was trying to make a scenario for the Db Br 101, driving from Dessau platform 3 to Leipzig Hbf, stopping at bitterfeld. However in Dessau, there is a red light, which prevents you from departing from the station.

Dessau platform 3 in the same custom scenario with the Db Br 146.2:
The weird thing about this bug is, that it only seems to appear, when the train in the platform is Db Br 101. When I switch the 101 with the Db Br 146.2 on the same route and platform, the light turns green as it should. I also tried this with the ICE 3M, and then the light also changed correctly.
