The status for this replication job shows as "finished" in the task list, but if you click on it you see it actually encountered the following error:

I'm fairly familiar with the lacking rights to a given property error so I tried allowing the replication user those rights on the destination. Oddly the property noted as being lacking isn't a valid property that can be assigned.

For example I've tried adding the property all these ways:
zfs allow -u rep-mad-file-01 org.truenas:managedby vol_1
zfs allow -u rep-mad-file-01 truenas:managedby vol_1
zfs allow -u rep-mad-file-01 managedby vol_1
zfs allow -u rep-mad-file-01 org.managedby vol_1
zfs allow -u rep-mad-file-01 "org.truenas:managedby" vol_1

In all cases I'm given this error:
cannot set permissions on 'vol_1': operation not applicable to datasets of this type

I've also tried apply the property to the exact dataset the replication is going into but the results are the same.

Debug is attached.
