Bank accounts

We have just had to create a new bank account in QB because our bank changed the system for updating the bank. Not a problem. We have a reconciled closing balance for the "old" account, we have transferred the funds in QB to the new account and the new one is also fully  reconciled. However in QB in the COA, when looking at the bank accounts, the old bank account shows a correct QB balance of zero but the "bank balance" obviously shows the last balance imported. This will never change but is annoying because the new bank account includes the old figure.

Can we clear the old bank account "bank balance" to zero ?

Thank you
