I moved your post to Elasticsearch channel since this is about the data reported by Elasticsearch.
Can you describe the exact steps you took to delete field "message" ? Maybe attach your logstash.conf. I would think that changing your logstash.conf only impacts new docs added to Elasticsearch and doesn't do any deletes.
It looks like you have either deleted and/or updated documents in the index, as both these actions would cause the deleted counter to be incremented. Are you letting Elasticsearch assign document ids, or do you set there in the indexing pipeline?
