Keyword subfield is blank

I am fairly new to grafana so I am hoping the issue I am having is an easy one.

I have fields that are keywords in elasticsearch, but the keyword is blank in Grafana. This Not an upgrade from a previous version as it is a brand new installation

The field also has the proper type in elastic:

Another user with a similar problem mentioned they manually entered the field, then it would populate. This does not work for me.

Why is this keyword field showing up blank in Grafana, but it is fine in Kibana?
