I was trying to test some of the prebuilt elastic detection rules with my Beat-Elasticsearch-Kibana setup. All other rules with simple query was working but the rules with event correlation was not working. I tried all possible troubleshooting and research but couldn't get to the conclusion.

Below is the query I was trying to test with required data from winlogbeat, sysmon.  
query = '''  
registry where event.type in ("creation", "change") and  
registry.path : ("HKLM\SYSTEM\_ControlSet_\Control\Print\Monitors\_",  
"HLLM\SYSTEM\ControlSet\Control\Print\Environments\Windows_\Print Processors\_") and  
registry.data.strings : "_.dll" and  
/\* exclude SYSTEM SID - look for changes by non-SYSTEM user \*/  
not user.id : "S-1-5-18"

My setup- Winlogbeat-Elasticsearch-Kibana.

Can someone please help here?
