Why does the trigger fire only once?

Question

Zabbix

Hello.

You need to monitor Event Windows Security with ID 4768.
Created an Item with the key - eventlog[Security,,,,^4768$,,skip]
Trigger -

logeventid(/Event User Log/eventlog[Security,,,,^4768$,,skip],,"4768")=1 and nodata(/Event User Log/eventlog[Security,,,,^4768$,,skip],2s)=0

How can I make the trigger fire every time this event occurs on the server, and not just once, as it happens now?
