Your winlogbeat mappings aren't installed properly probably. See this thread for troubleshooting steps:

> Hi @aura, as you've discovered, it seems that some of your fields are not being mapped to the correct Elasticsearch [datatypes](https://www.elastic.co/guide/en/elasticsearch/reference/7.6/mapping-types.html). Elastic Common Schema (ECS) specifies that fields such as host.name must be of the [keyword](https://www.elastic.co/guide/en/elasticsearch/reference/7.6/keyword.html) datatype. Indeed, as you've also discovered, Elastic SIEM relies specifically on host.name to be present as a condition for populating many visualizations with host data. I'm not sure how familiar you are with Elasticsearch [mapping](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping.html) and [index templates](https://www.elastic.co/guide/en/elasticsearch/reference/7.6/indices-templates.html), as they can be challenging…
