SEMANTIC containing a dot character not working

[CerxMe]

Grok patters should be %{SYNTAX:SEMANTIC}
When the SEMANTIC value contains a dot, no outputs are parsed as is expected.

NO DOT:

HAS DOT:

Also experiencing this testing some grok's intended for Elasticsearch. This platform cannot handle dot's in the semantic. I thought the pattern repository was broken at first.

I've seen the same issue too, tried coming up with workarounds, but so far just ended up replacing dots with underscores. This works but is far from ideal.

I also experience this and would highly appreciate a implementation of semantic syntax
