Thank you so much for posting here.
We are wondering whether it is replication error 8614? If so, we could follow the link to solve this issue.
As mentioned, we have checked that there are no lingering objects. We could try the solutions mentioned in the link. On this affected DC, set "Allow use of divergent and damaged partner replication" to 1 in the registry. This setting allows DCs whose replication time exceeds the tombstone lifetime to synchronize data.
Besides, ensure that strict replication consistency is enabled. Strict replication consistency ensures that lingering objects will not be replicated. For more detailed information, we could refer to the above link.
Please backup the DCs before the operations.
For any question, please feel free to contact us.
