Excluding certain usernames from Failed Logins exception report

Excluding certain usernames from Failed Logins exception report

Hello

I am using ELA v10 on Windows

I have a Failed Logins report that is reporting exceptions

However I want to exclude reporting of failed logins from certain usernames.

When I add an exception for each username I want to exclude, no failed logins are being reported

The logic that I have is:
Event ID = Predetermined Events
AND HOSTTYPE equals Windows
AND Username not equals User1
AND Username not equals User2

Would appreciate suggestions on how to troubleshoot

Thanks
