Hi, I am using
```auto
kv { }
```
filter but output in Kibana have tag `_grokparsefailure`, why? Output looks like is fine, without errors however still have this tag, when I even don't have grok (only input udp, filter kv and mutate for remove field and output to ES).
Sometimes also there is `_jsonparsefailure`, when there is no json in config and data source, why?

That suggests you are not running the configuration you think you are. Try adding`--log.level debug --config.debug` to the command line and see what configuration it is loading.
