Possibly wrong price generated

[ljrk0]

The following request

https://bahn.guru/day?origin=Berlin%20Hbf&destination=LYON&class=2&age=A&date=26.09.2023

generates a price of 69,90 EUR for Berlin Hbf through Erfurt and Baden-Baden to LYON from 9:34 to 19:56.

The search on bahn.de directly yields a price tag of 112,90 for that connection, however:

Any idea what's going wrong?
