It was from a cancellation of a ticket. But I received a voucher in my email now :)

@bahn.de Hi, I want to use my voucher of 110,99 for a seat reservation but I see this. Can I use the voucher after this reservation or is the voucher (and my money) gone?

Yeah I know, but for other tickets (like Nightjet reservations and stuff)

And is it possible to use a Gutschein at the DB Reisezentrum?

@bahn.de Hi. I had to cancel a train ticket and have a voucher now. Can Is use this voucher for the payment of a Deutschland Ticket?
