Can you provide a more specific version, i.e. 4.x.y? The reason I ask is because it looks like this issue was [reported](https://github.com/elastic/kibana/issues/3610) in versions 4.0.3 and 4.1.1 and [fixed](https://github.com/elastic/kibana/pull/3960) in versions 4.0.3 and 4.1.0.

Thanks. I would suggest upgrading to _at least_ 4.0.3 as this bug was fixed in there.

Ideally, thought, you should upgrade to the latest version of Kibana. 4.0.2 is quite an old version (released about 1 year and 3 months ago) and a lot of new features and bug fixes have been released since them.
