Hi, you seem to be using external_labels without alert_relabel_configs to drop this label from your alerts again. Therefore, your alerts will have different labels and will not be de-duplicated.
See this blog post: https://www.robustperception.io/high-availability-prometheus-alerting-and-notification It has an example for the dc label (where you would need replica).
