Setting default index in Kibana 4

I can't define default index in Kibana 4.0.2, as you can see on the image below. It doesn't saves if I enter it manually in "Advanced" tab, it only glitches when I click on "Set as default index" button but it doesn't make needed changes.

I'm using Couchbase 3.0.3, transport-couchbase plugin 2.0, ElasticSearch 1.5.2.

I've tried reinstalling everything (except couchbase), one by one, always the same. I've googled it whole day, nothing. Someone has any idea?

Here is how it looks:

Solved it.

After changing couchbase_template.json it's needed to set

curl -XPUT http://localhost:9200/_template/couchbase -d @/usr/share/elasticsearch/plugins/transport-couchbase/couchbase_template.json

Then it should work.
