Purchase order history is missing from the P/O tab after upgrading from 2019 SQL to 2022 SQL

No purchase orders are appearing in the P/O tab after go live. The AP and PO settings to retain PO history are enabled. When I look at vendors in old and new versions, the P/O tab in 2019 does show multiple POs. 

I queried the PO_InvoiceHistoryHeader in both SQL instances and they're almost identical, with the 2022 version showing more records, due to PO entry done after go live. Is this a known issue? I will rebuild the sort files later this evening, hoping that may help. I already tried to run the create PO history utility, but that didn't help. 

Any suggestions.
