Kibana adds filed

Hello, everyone. I have been building an elk environment recently, but I have encountered a problem. My logstash agent output log is as follows:

{
         "level" => "WARN",
          "uuid" => "109933",
          "path" => "/usr/local/deploy/intelligent/logs/spring.log",
      "@version" => "1",
    "@timestamp" => 2018-11-14T09:37:47.483Z,
          "type" => "znpz",
     "timestamp" => "2018-11-14 17:37:31.345 ",
       "message" => "2018-11-14 17:37:31.345  WARN 109933 --- [AlarmTimer] c.c.i.service.Impl.ShowIpranServiceImpl  : ip:NeName = 1233-NGN-SW3-XZ-S9306-A",
          "host" => "ZNZD-CORE"
}

you want the level field to appear in the kibana management interface, but there is no display, such as screenshot

ask God for guidance
the specific configuration is as follows:

logstash agent:input {
    file {
        path => ["/usr/local/deploy/intelligent/logs/spring.log"]
        type => "znpz"
        discover_interval => "15"
        sincedb_path => "/opt/deploy/logstash-6.4.3/.sincedb"
        start_position => "beginning"
    }
}
filter {
    grok {
        match => { "message" => "%{DATA:timestamp} %{LOGLEVEL:level} %{DATA:uuid} %{DATA:message}" }
    }
}
output {
    kafka {
        bootstrap_servers => ["XXXX"]
        topic_id  => "znpz"
        compression_type => "snappy"
        codec => "plain"
    }
   stdout {}
}
logstash server :
input {
    kafka {
        bootstrap_servers => ["172.25.241.229:9092,172.25.241.230:9092,172.25.241.231:9092"]
        auto_offset_reset => "latest"
        topics => ["znpz"]
        codec => "plain"
        consumer_threads => "3"
        decorate_events => true
        type => "znpz"      
    }
}
output {
    elasticsearch {
        hosts => ["172.25.241.229:9200"]
        manage_template => false
        index => "logstash-%{type}-%{+YYYY.MM.dd}"
        document_type => "%{type}"
    }
}
