On a resharded bucket that is upgraded from pre-12.2.2 -> 12.2.4 where teh bucket stats were double accounted because of http://tracker.ceph.com/issues/22124, --sync-stats will have this issue that every sync stat operation will drop the entries from the older reshard. As an example

$ ./bin/radosgw-admin user stats --uid=testid  --bucket testbucket
