master/master replications v. 2.2.32

Hi, in the past I set up a master/master replication through TCP using dovecot 2.2.10 on both servers and everything is running fine, I filter the users to replicate using the iterate_query on file dovecot-sql.con.ext; now I want to set up a new replication between two new servers running dovecot 2.2.32 but the replicator service tries to replicate every user on my database even when the iterate_query is correctly set up and the command "doveadm user '*' " shows only the users I want to replicate, I think I am missing something but I do not know what.

Thank you so much for your help.
