Hi:

I found that the auto merge feature have a issue on kylin 2.2.0:

https://issues.apache.org/jira/browse/KYLIN-3165 
<https://issues.apache.org/jira/browse/KYLIN-3165>

And this issue have been resolved in kylin 2.3.0.

 If you want to use the feature of the auto merge, you can upgrade to 2.3.0 or 
the latest version.
