How to redeem this credit? Is it lost or can i use it somewhere else?

I lost my parking ticket and selected lost ticket in the payment machine. The fee was 22€. As i put the first 20€ before i could put the rest of the money this ticket was printed. I couldn’t scan it anywhere. The machine didn’t read it. What does this ticket mean and can i use it as a way to pay another time? It mentions a kasse but there wasn’t any except the one at the exit which also couldn’t read it. Thanks for your help!
