Banking Transactions Report for Visa Account showing “Unallocated” against Historical Transactions – MYOB Business Pro

I have seven transactions showing in a Bank Transactions Report as Unallocated. The Report is for a Visa Account. They are all against the same supplier but not all transactions to that supplier are “Unallocated”. The ones that are, are all in the period 18/10/2021 to 18/05/2022. Not all transactions in that period are affected.

I have run a Supplier Transactions Report for the supplier concerned for a period 13/5/2019 to 26/01/2024 and focussed on the “Purchase” transaction type and traced them back to the original Bills. I have then linked the payments shown against each bill to the corresponding entry on the Supplier Transaction Report. These payments are shown as “Spend Money” transaction type in the report. The closing balance of the report shows the correct balance outstanding to the supplier.

This process has confirmed that each of the bills for the supplier has been paid via Visa account.

Has anyone got ideas as to why the transactions are shown as Unallocated?
