PI Email Alert Configuration - Multiple Alert in Adapter Engine

Hi,

My SAP PI alert emails are now working. However, when I get an error in the Adapter Engine (RWB),MULTIPLE OF EMAIL ALERTS are being sent. When an error occurs in Integration Engine, only 1 email alert is sent.

For the Adapter Engine Alert Rule, i have checked the 'Suppress Multiple Alerts of This Rule' and i didn't receive any emails, but when I unchecked it, i receive multiple emails.

im using PI7.1 SP08. is there an effect because my SP is not updated?

thank you.
