Replication not sync all table coloumns content

[davide marchi]

Hi Friends,
I'm using Replication on two Debian Jessie VPS.
Both MySQL version: 5.5.59.

I've a db named foo and into this db 6 tables, and into the table "virtual_domains" columns: id name selector privatekey publickey

Adding on Master a value for privatekey this is synced,
but adding on Master a value for "selector" this is not synced.

I've try o restart both mysql server and force slave replication reload:

STOP SLAVE;SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1;START SLAVE;

without success.

Where I could verify this issue?

many thanks!

Davide
