This looks like an issue from a year ago. Have compared the bank account account number with the last 4 digits of the bank account linked with your PayPal account? Do they match? Have you tried to reach to your bank already? What was their asnwer?
I would recommend you calling PayPal Customer Services by clicking onto Contact us on any PayPal page as they will be able to review this for you, as regrettably we can’t see your account details here.
