On-Account receipts getting exception after Invoice is applied - "Unprocessed" & "Receipt Updated"

We have been experiencing a high volume of exception in receipt application after moving from On-premise to OCI.

Users create receipt batches with on-account receipts. They run accounting on it after the batch is created. The next day they unapply the on-account receipt and then save. Then they add line to apply the invoice to the receipt and run accounting.

Look at the diagnostics, a new XLA event is created which is not being picked up by Submit accounting. We have been applying datafix to these transactions at month-end but cant find root cause of the issue.

Any insight would be greatly appreciated.
