Hi,

I'm trying to drop certain fields using filebeat's `drop_fields` processor, so that they will not be indexed to my Elasticsearch. I'm using version 8.8.0 for both filebeat and elasticsearch.

Most of the fields specified in the `drop_fields` array are dropped, but a few are not, e.g. `source.geo.city_name`, `destination.geo.location.lon`, and `network.direction`. Except for `network.direction`, all the field names that were dropped only have one period in them, e.g. `abc.def`.

A portion of the relevant configuration in `filebeat.yml` is

```auto
processors:
    - drop_fields:
          fields: ["destination.bytes", "destination.geo.location.lon", "ecs.version", "source.bytes", "source.geo.city_name", "network.direction", "source.packets"]

```

Why are some of these fields not dropped?

Thank you.
