Delegate receives an email while the user doesnt

[VaranAwesomenow]

I have a scenario where I made a user A as delegate to User B, user A gets the email but not user B, below are further details

1. Notification = Incident Opened and Unassigned

Guillermo Frohlich has subscribed for this notification but has added an additional filter which is to as per below screenshot

Added Abel Tuter as delete to Guillermo Frohlich

Based on the above personal subscription -> Send when condition no email should get sent when an incident is created that doesnt have priority as 1, but the email got sent to Abel.tuter

Email log shows below, which states that notification got sent to abel tuter and wasnt sent to Guillermo Frohlich

Wonder what is causing this behavior
