Windows Event Log - NODATA - not clearing trigger

[ahahum]

I have several servers setup with triggers based off of the windows event log. 1 in particular is not clearing the trigger after the entry matches and I suspect it is because the log itself only has entries when there is an error. There is never another message logged in the log other than the ones I'm interested in.

My trigger is:

{hostname:eventlog[logname].logseverity(0)}=4 or ({TRIGGER.VALUE}=1 and {hostname:eventlog[logname].nodata(10)}<>1)

I use this same setup for all my other logs and it works great - the trigger fires, then it clears soon after. But for this particular log, it is always triggered after the initial trigger.

How can I make this one trigger, then clear?

Thanks!
