SQL Alert 1480 Not firing for a Particular database

All,

I set up an Alert for Message Id 19406 to be alerted whenever the Failover/FailBack on our AAG happens. I also setup an Alert for Message ID 1480 when a particular database's role changes. I need this Alert to work since I have to enable TRUSTWORTHY on some of the databases that are on the nodes (Secondary when the Failover happens and Primary when the Failback happens). I created this Alert by selecting the Database Name while configuring the Alert.

The Alert for MessageID 19406 fires as expected and we get a total of 12 alerts (per Failover & Failback). Unfortunately, the alert for Message ID 1480 does not seem to happen for the particular database. Instead I get one email for every database in the AAG.

I'm not sure if this is how it is supposed to work. I cannot even specify the database name in the Message Text area since I have more than one database for which I need to change the TRUSTWORTHY setting. I was hoping to run a Job via the Alert to enable the TRUSTWORTHY setting.

Please kindly share your experiences!!

Thanks.
