There were around 23M documents in our couchbase cluster B out of which we have deleted 21M documents.
We loaded fresh copies of these 21M documents in another couchbase cluster A.
Now we enabled XDCR from cluster A to cluster B but looks like no copy of data is happening.
When checking XDCR logs on source cluster which is A we find this interesting lines

Despite deleting the document from couchbase how is this document key still known and its meta() information still available ? Is it because of the fact that revSeq is higher XDCR is not copying the document to cluster B?
How can this problem be solved?
