mysql replication fail (no error)

I'm doing a replication on a mysql 5.6 server (master) to a slave in mixed mode. The thing is, i connect to mysql trought workbench, i execute querys and are replicated. But if another user connected through the same way, deletes a register, it is deleted on the master, but not replicated on the slave. So the register stills appear. I don't understand why it doesn't shows an error. It continuous replicating till some tries to insert a register with the same ID (as it is not deleted) and then it fails showing a duplicate entry.

Does anyone knows how to se a log where it shows the errors? Why it continuous replicating and not executing that query?

Thank you
