Logstash Aggregate filter plugin Not working properly

Question

Hi i am new to logstash and was trying the demo in their documentation here https://www.elastic.co/guide/en/logstash/current/plugins-filters-aggregate.html#plugins-filters-aggregate "example-1" i was using the same exact script and input but still got different output because of this i was expecting single entry in kibana but it shows 3 entries please help

   grok {
     match => [ "message", "%{LOGLEVEL:loglevel} - %{NOTSPACE:taskid} - %{NOTSPACE:logger} - %{WORD:label}( - %{INT:duration:int})?" ]
   }

   if [logger] == "TASK_START" {
     aggregate {
       task_id => "%{taskid}"
       code => "map['sql_duration'] = 0"
       map_action => "create"
     }
   }

   if [logger] == "SQL" {
     aggregate {
       task_id => "%{taskid}"
       code => "map['sql_duration'] += event.get('duration')"
       map_action => "update"
     }
   }

   if [logger] == "TASK_END" {
     aggregate {
       task_id => "%{taskid}"
       code => "event.set('sql_duration', map['sql_duration'])"
       map_action => "update"
       end_of_task => true
       timeout => 120
     }
   }
 }

INPUT

 INFO - 12345 - TASK_START - start
 INFO - 12345 - SQL - sqlQuery1 - 12
 INFO - 12345 - SQL - sqlQuery2 - 34
 INFO - 12345 - TASK_END - end

  "sql_duration" => 46
}
