Subscription blocking rules are not effective #3023
Description
Question and Steps to reproduce
I conducted a test for label selection exclusion. The prompt event label does not match. Could you please tell me how to set it up?
There is a host in a project, but when I subscribed, I didn't want to receive alerts for a certain tag. So I set "not in" and "!" And! ~ All attempts have been made. Those containing that label will be filtered out. Messages without this label will not trigger an alert.
Relevant logs and configurations
