Trying to set up a FORTI-WEB email policy to only send mails of Critical attacks

I created a new EMAIL POLICY under Log&Report -> Email Policy and  named it WAF-CRITICAL, set the log level to Critical , set up the SMTP sender and myself as the recipient and saved it.

I then went to Trigger Policy, Create New gave it a name and under email policy drop down i selected WAF-CRITICAL which is the email policy.

I started receiving emails but not for Critical level attacks but for low level attacks instead , basically every single event is being emailed to me instead of only Critical Attacks.

I am running FORTI-WEB v7.2.10 build409 (GA)

These are the kind of alert emails im receiving:

How do i set this up to only mail CRITICIAL attacks and not overwhelm my emails with low level attacks?

Also under Log&Report -> Log Config -> Global Log Settings i have enabled "Alert Mail" slider and set log level to "Critical" on the drop down.
