Value found in extractor not exist in full message

in specific stream -> Value found in extractor not exist in full message .

Hi, you right , my mistake .I add all info , :
I have server with nxlog that monitor text files and transfer to graylog on the same server.
variables in file separate by semicolon (;), so i used “split and index” to create extractors - very simple .
Now i see that extractors include value that not inside of full message, they cuts from other row in stream ?
My GRAYLOG IS 2.4 version, I use same way to split for many inputs and only one with this problem.
I create new extractor in the same way and it is work OK. something go wrong with old extractors.

I guess you might have configured something wrong …

You provide NO detail of anything - that is why you could not get any help over here.

Check your extractor configuration, especially Extraction strategy, if it is Copy and not Cut.
