Multiple Sites with same bank account in iSupplier

Hello,

I have an iSupplier user who created several new sites on their record, and then added the same bank account to each of those sites.  When the Supplier user then accesses Supplier Bank Account Requests in order to review/approve, there are not any Account Requests  - only Account Assignments for each of the new sites, and the Supplier user has no option to take approval action.  The page displays:

The account assignments cannot be approved since the account requests associated with the assignment have not been approved. Please process all the account requests before processing the assignment requests.
