Deleted Extractor Still Visible/Running

Hello Graylog Team,

I had created a test extractor and then deleted it. But I still see the extractor on messages.

What is the correct way to delete an extractor after it was created.

What I have done
Deleted the extractor and restarted Graylog Server - but no luck

Is there some caching issues ??? that causes this

Currently using version 3.1

maybe your messages are not in “time sync” so you have the impression the extractor still runs. At least that is what I have seen in the past.

In other words - I never have seen that extractors are not deleted proper.
