Mysql replication problem after export/import on already working replication

I have 2 databases in master - slave replication.

I had some errors in the replication due to inserts in the slave, so I corrected it and executed:

stop slave;
set global sql_slave_skip_counter=2;
start slave;

After it, I saw that my change wasn't correct so I decided to export the database and import it to the slave.

Now the show slave status seems ok:

But if I change anything on the master I don't see the change in the slave. Any suggestions of what can be wrong?
