Hello everyone,

I encoutered a very strange behavior causing query error due to invalid type.  
On a project I create several indexes with the same mapping, but different names

```
    "anSampleOriginalIndex" : {
    "mappings" : {
      "properties" : {
        "action" : {
          "type" : "keyword",
        },
        "device_type" : {
          "type" : "keyword",
        },
    }
}

```

But some indexes found out with this mapping

```
"indexAltered" : {
    "mappings" : {
      "properties" : {
        "action" : {
          "type" : "text",
          "fields" : {
            "keyword" : {
              "type" : "keyword",
              "ignore_above" : 256
            }
          }
        },
        "device_type" : {
          "type" : "text",
          "fields" : {
            "keyword" : {
              "type" : "keyword",
              "ignore_above" : 256
            }
          }
        },
    }
}

```

As you can see all my properties became text with a keyword field instead of the original mapping.  
Dynamic mapping is disabled on each index.  
The only difference I notified in kibana' index management page, it's replica for the altered mapping indexes was set to 1.

How come it be possible without dynamic mapping?

Thanks in advance!

I reply to my self, i feel very stupid!  
My admin never create this indexes so, it's not about dynamic mapping on index but dynamic index created
