Anyone else getting this warning / error on contionuos replication?

I think this is related to using "Distribute replication accross the storage repositories" option
This is happening on my daily replications using 4 storage repositories on the destination pool. The replicated VM snapshot doesn't get updated (at least the timestamp on the description doesn't). I also think that the replication is failing because the log does not show any data transfer to the storage repositories on the destination pool.

In case it has something to do with this: On the same job I'm also doing delta backups. Other options are NBD, CBT and merge backups sinchronously. Replication retention is set to 1 on the job schedule, which is called from a job sequence. Storage repositories are lvmoiscsi.

Thank you,
Pedro
