Hi, I'm trying to ingest data and use auto discovery. When I look at the mappings my field is discovered as long. I guess that this is ok as it's an integer.

```auto
      "ResolveTime": {
        "type": "long"
      },

```

But when I go to Discovery and look at my data Kibana says **Unknown field** :

I don't know why it says unknown field and how to fix this. As I need to do some math with it.

It fixed itself. Don't know why it now shows all fields as numbers.
