Why does AutoReversal job fail to reverse few journals at period close even when they meet criteria

We encounter an issue every month where most accruals and other journals reverse correctly based on the defined reversal criteria, but the system occasionally leaves some journals unreversed. As a result, our operations team must manually review the subsequent period to identify any prior-period journals that still need reversal. This manual intervention should not be required if the scheduled job consistently picks up and reverses all entries due for reversal on the last day of the period.

Has anyone else encountered this issue or has any insights or updates on it?
