Parking Ticket/Certificate of Release?

Can anyone help with this? Trying to renew my registration and I see there's a registration stop from parking tickets. Issue is I have a permit to park in said lot so none of these are even valid tickets. It says I can pay $7 for a certificate of release. What does that mean? Anyone have any insight? Should I try to appeal? These are really old and I never received a ticket for these on my car and don't recall getting letters for these tickets in the mail. Anything helps!
