Cannot stop sentry massive regression emails

Hi sentry team,

One of the project has lots of regression email spam, and i do not have any way to stop this kind of notification email stream

Here are my account notification setting, i also set workflow Nothing and un-check the Alert option, does not help

Here is my project setting for Rule, tried but it does not help

Regressions are not alerts – they are classified as workflow emails (it works just like your favorite project management tool). You’ll need to disable the relevant settings and/or unsubscribe from the issues you’re receiving emails about.

so I set this in my notification account setting
it should stop spamming to the mail right ?
but it does not
