When added new field through Kibana in the Index Template I opened **Advanced Options** in **Mappings**

after that extra fields (Highlighted in the Image) came in the Index Template after adding the fields.

If I remove those manually through Dev Console will it create an issue to the Index?

```auto
PUT _index_template/jee-development-filebeat
{
  {
  "template": {
    "mappings": {
      "properties": {
        "mdc.duration": {
          "type": "integer"
        },
        "mdc.price": {
          "coerce": true,
          "index": true,
          "ignore_malformed": false,
          "store": false,
          "scaling_factor": 99,
          "type": "scaled_float",
          "doc_values": true
        }
      }
    }
  },
  "index_patterns": [
    "jee-development-filebeat*"
  ]
}

```

Another doubt - can be manually change between active ands non-active master nodes \>
