Avamar replication jobs not terminating "gracefully" at end of schedule window?

Working with a customer and we are seeing some Avamar replication jobs that are not terminating "gracefully" at end of their schedule window, which results in a "Failed" status on the destination Avamar, but only a "Timed Out - End" status on the source Avamar.

If all jobs were performing like this, it might be easier to troubleshoot, but only a few are exhibiting this behavior - others are indeed cancelling "gracefully" and showing "Partial Replication" status on both the source and destination Avamars. And FWIW, all of these replications are related to a single Data Movement (Replication) policy.

Also, not sure if this is related, but all jobs on the replication destination are showing the "Overtime enabled" indicator (including the ones that are completing), while they do not show a similar overtime indicator for the job on the replication source.

Log info for one of the "Timed out / Failed " jobs from the Avamar replication source:
