PC Hma: Missing Double Ice Services In Menu

One example:
ICE 596 Berlin Hbf Tief in Journey

Steps to reproduce:
- Spawn on foot in München Hbf at 11:45, ICE 596 is waiting at platform 13.

All other double ICE services (16 cars) are also missing in the menu. The named example is especially noticeable because it is included in the journey.

 

I was wondering why I never managed to get to drive a double ICE, but I always see them on the track
