If you have MultiMaster Replication, every DB server needs this

    [mysqld]
    log-slave-updates

This will [tell a Slave to log completed SQL commands from the Relay Logs into the Slave's binary logs][1]. Just add that option to every Slave and restart mysql.

If this does not work, you may need to explain more things to us.

Here are my other posts where I suggested using [log-slave-updates][1]
