How to disable nested data type keyword in dynamic mapping

hi David,

thanks for the quick reply. I am getting below as a result of get mapping:

{
  "myindex": {
    "mappings": {
      "mytype": {
        "dynamic_templates": [],
        "properties": {
          "24 hour timer": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          },
          "BRAND": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          },
          "COLOR": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          },
