Event Log Forwarder - Where is the Audit Failure Type?

Hi There,

I'm trialing Kiwi Syslog and I'm having trouble with the Log Forwarder and Security Event Log.  When I click on the Security Log I don't see Audit Success or Audit Failure as an event type.  It just has Error, Warning and Information.  If I manually edit the CFG file and add <int>16</int> it works, but then it gets overwritten if I make a change.  Am I doing something wrong?  How can I see Audit Failure as an Event Type?
