Audit event for remove node is incomplete and malformed

Remove node event definition in audit_event.json
{
"id": 8197,
"name": "remove node",
"description": "Node was removed from the cluster",
"sync": false,
"enabled": true,
"mandatory_fields": {
"timestamp": "",
"real_userid":

{ "source": "", "user": "" }

,
"remote":

{ "ip": "", "port": 1 }

,
"node": ""
},
"optional_fields":

{ "sessionid": "" }

}

Actual event printed in audit.log:

{"timestamp":"2015-02-04T23:13:12.395-08:00", "id":8197, "name":"remove node", "desc":"Node was removed from the cluster", "node":"ns_1@172.23.107.64", "real_userid":"anonymous"}

Mismatch is the fields of event definition and actual event printed.
