I don't use the "logs app" in Kibana, so I'm afraid I'm limited in my
ability to help you.
That being said, the thread you mention has been solved by changing the name
of the message column by the user:

   You are right! My problem was that I was changing "message" field to
   "message_log", so really "message" field didn't exist.
   I have changed in Kibana Logs the "Log Columns" to add "message_logs" and it
   works now!

So it seems you can change the name of the columns in kibana, and in your
case, assuming you're using the default syslog-ng config, it should be
MESSAGE.
