"Charterzug" not showing up in Träwelling

[Quadrubo]

Describe the bug

Today I will be traveling with a special train by the "Berliner Eisenbahnfreunde e.V.". I did not expect to find this train on bahn.expert but I did.
Then as I wanted to check in, I couldn't find the train in Träwelling.

If this is an issue, I would gladly help debugging it on future trips.

Steps to reproduce

Try to check in from "Berlin-Lichtenberg". Look at the trips at 13:16.

As this is related to the old data provider we were using and it's out of our control, there's nothing we can do about it.

can this be converted into a discussion and be kept open? imo this never was related to the old data provider, but more to a potential RIS data provider?
