Supplier bank account default at installment even when payment method is check

Summary:

The supplier can be paid via check and ACH. The bank account has been setup at supplier site in cases when the supplier needs to be paid via ACH. But some payments are made via Check.

When the default payment method is set to Check at supplier site level, for invoices that are created after this change, payment method is defaulted to Check but supplier bank account is also defaulted in installment. This should not happen. Is there a way this can be fixed?
