Winlogbeat Object Value are not equal to Event In Windows

[lcosta (Luis Miguel Costa)]

Good day,

I configured my graylog-sidecar, to send DNS events from my Domain Controller:

# Needed for Graylog
fields_under_root: true
fields.collector_node_id: ${sidecar.nodeName}
fields.gl2_source_collector: ${sidecar.nodeId}

output.logstash:
   hosts: ["10.100.1.20:5044"]
path:
  data: C:\Program Files\Graylog\sidecar\cache\winlogbeat\data
  logs: C:\Program Files\Graylog\sidecar\logs
tags:
 - windows
winlogbeat:
  event_logs:
     - name: Security
       event_id: 4662

The Event Values:

Object:
Object Server: DS
Object Type: dnsZone
Object Name: DC=nostromo.com,CN=MicrosoftDNS,DC=DomainDnsZones,DC=nostromo,DC=com
Handle ID: 0x0

The Winlog Event Value:

Object:
Object Server: DS
Object Type: %{bf967a8b-0de6-11d0-a285-00aa003049e2}
Object Name: %{3f936758-2a36-41a2-a47a-96675c1a0537}
Handle ID: 0x0

Not understanding why this value is not equal, is there something “enconding” the values?
