Nelnet thinks Im in School Still

So I graduated in May 2025. I had to take out a GradPlus loan in 2024 to pay for living expenses. Nelnet thinks Im in school until 2028 so I have no payments.

I figured they'd eventually correct it and left it alone, but they haven't. I finally sent an email about it through the portal but I figure it will be awhile before I hear back. I understand this is a common issue with Nelnet.

I am just worried about the credit implications from their mistake. Anyone face any delinquencies or massive back payments from this?
