Expected results:
No error and CLI Script should be executed if alert condition occurs.

Additional info:
This appears to be confined to an alert definition being defined on a group. When defining the exact same alert definition on an individual resource, all is well. Additionally, if changing from **Myself** to entering my own user name and password, all is fine on the group alert definition.
