Loans paid off in 2018 just got “reinstated”?

Hi everyone! I’m hoping someone here has seen this before because I’m a little stressed.

I fully paid off all my student loans through Nelnet back in 2018. This morning, I woke up to a random email from them saying my "student loan statement is available." I thought it was a glitch, but when I logged in, all my old loans have been reinstated with full balances.

The status for all of them says "Admin Forbearance."

I did submit a Borrower’s Defense application in 2022. When I called Nelnet, they told me that because my loans were already paid off, they had to "re-open" the accounts to process the discharge and get a reimbursement in the future? I honestly forgot i submitted an application.

Has this happened to anyone else who had already paid in full?
