PC Arosa Linie Signal Issue Untersax?

Driving the 6:51 feigth service from the Rhb enhancement pack, I approach Untersax from Chur. The signal before Untersax shows green, but then the exit signals from Untersax show Red. I am wondering if this green signal aspect is correct. In Untersax you see the exit signal only from a very short distance, in fact to late to come to a stop from 30 km/h.

It would feel more natural if the previous signal would show yellow. It would be safer anyway.
