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. 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
