**Steps to replicate the issue** (include links if applicable): Open the Karma UI at https://alerts.wikimedia.org/ **What happens?**: Some alerts are shown twice, once with receiver=default and once with receiver={customreceiver} This only seems to happen for alerts with severity=default. Example: {F41600591} This alert has severity=critical and a custom receiver (though it is not shown in the screenshot for some reason) and is only displayed once: {F41600593} **Other information** There is a related issue upstream (https://github.com/prymitive/karma/issues/5144) but I think that describes a different problem, when an alert is displayed twice with two custom receivers, not one custom receiver + the default one. An example would be this one: {F41600597}
