Payables Payment Request Import-How to unlink the Account Number from the Bank Name and Account Type

We imported a one-time payment to AP, using the Payables Payment Request Import template, however, the Account Type and Bank Name were incorrect. Then, when we import the one-time payment to AP with the corrected data, the transaction is imported again with the wrong data loaded the first time.

I understand that the account number has been linked to the name of the bank and the account type

I would like to know how to unlink the account number from the name of the bank and the type of account that was charged for the first time to load the transaction with the correct information.
