Weird issue; we have rules to send alert notifications to Slack; the issue is when using our enterprise grafana v9.1.3 it sends 4 alerts every time. However, when cloned and executed through a local deployment of Grafana v9.1.3 it sends 1 slack message (as expected) to our Slack channel.
All of the settings we can control are identical
See below -
4 failures (Enterprise Grafana)
1 failure (Local Grafana) - Same alert failure
