Bi Directional Replication/mutations failed resolution


I have two clusters of Couchebase Community (4.1.0-5005) set up . With bidirectional replication, between the buckets. on each server.

I am updating binary log files via a “append” operation.
After the append operations my “mutations failed resolution” count goes up.
Though the changes appear to have been replicated between the clusters.

I know I am not running into a concurrent modification issue, because each file is only ever modified by one cluster. Any clues on what this could be or how to mute these errors so that we can see when we actually do have issues with changes replicating from one cluster to another? so that the “mutations failed resolution” statistic becomes meaningful again
