Unlinking the account from a cancelled bank account

Hi MYOB Team!

We recently added new bank accounts to the system and have cancelled the old ones. The problem is that we cannot link the new bank account to the account which we've linked to the cancelled bank accounts to. There is a notification that pops out which says that "Account cannot be duplicated. Please select a different Account."

Can you please assist us on what we should do in order to link the new bank accounts to the account in the balance sheet?

Thanks
