Hello  
We are encountering an issue while trying to set the `_tier_preference` in an index template. Despite updating the setting in the index template edit page, the preview shows that `_tier_preference` is set to `null` instead of the expected value `data_hot`.

Here is the JSON snippet we are using in the index template edit page:

```auto
{
  "index": {
    "lifecycle": {
      "name": "test-ilm"
    },
    "routing": {
      "allocation": {
        "include": {
          "_tier_preference": "data_hot"
        }
      }
    },
    "number_of_shards": "4",
    "number_of_replicas": "1"
  }
}

```

And here is an extract of the preview

```auto
{
  "settings": {
    "index": {
      "lifecycle": {
        "name": "test-ilm"
      },
      "routing": {
        "allocation": {
          "include": {
            "_tier_preference": null
          }
        }
      },
      "number_of_shards": "4",
      "number_of_replicas": "1"
    }
  },
  ...
}

```

We know the `_tier_preference` is not setting to `data_hot`, because whenever an index is created, it's tier preference is `data_content` (he default value).  
Does anyone have any insight on what could be happening?  
Extra information:

- We are using Elasticsearch 8.11.3.
- Our cluster has four nodes: two hot zones and two warm zones.

Thank you in advance,  
Sebastián
