Hi everyone!
 

My friends and I bought a One Country interrail pass a few weeks ago. Since we want to travel from Switzerland to Florence, we had to make seat reservations (Trenitalia). I bought these also via the Interrail website.

But later we realized that we bought the wrong pass. So we cancelled it and bought a new one (Global Pass). When I checked the tickets from Trenitalia today, I saw that the number of our old pass is still noted there.

I assume this will cause problems at ticket inspection? Is it possible to change this and rewrite it to our new number?

Kind regards,
