Discovery - time not update after update ES document

My logstash output (elasticsearch) plugin is configured to update documents. Everything work well but in time of update document time field in discovery view don't update automaticaly (I have set auto-refresh option in kibana view). New time value appeared after reload save search or manual page reload.In table view timestamp is updated but not on main view.

First event:

Second event which should deduplicate but with time update

My logstash config:
input {
file {
path => "/xxx/xx/log/xxx.log"
codec => json
stat_interval => 0


filter {



    fingerprint {
            source => ["field1", "field2", "field3", "field4"]
            target => "[@metadata][generated_id]"
            key => "my-key"

output {
stdout {
codec => rubydebug { metadata => true }

    elasticsearch {
            host => localhost
            action => "update"
            protocol => "http"
            document_id => "%{[@metadata][generated_id]}"
            doc_as_upsert => true


I'm ELK beginner and could you help me if its is my logstash config issue or Kibana issue?

Kibana: 4.1.2
ES: 1.7.1
Logstash: 1.5.4

It seems like a refresh bug, potentially. I'd suggesting filing it in Github:
