Description (partial)

Symptom:
If there is more than one Negated IP/Subnet in the Original Client IP search filed for Intrusion Event, all Intrusion Events with no OCIP (XFF) are ignored as well. 
This appears to be an issue ONLY if the search include more than one NEGATED search. 

Example: 
Event: Intrusion Event 
!10.10.10.10 OR !10.10.10.0/24- This will NOT exclude IPS events with No Original Client IP.
!10.10.10.10, !5.5.5.5 - This will exclude IPS events with no Original Client IP.

Conditions:
6.2.x  SW version
