Recovery Alert Firing, With No Down Alert

I am trying to track down an intermittent issue where an alert rule is setup with a 5m delay:

…but a recovered alert is issued if the device goes down and then back up within that 5m delay.

No down/critical alert is ever issued (as expected), so the recovered alert is confusing for its recipients.

Any ideas how to fix/change this? Many thanks.

Hmm, I discovered the same issue today. I’m running 21.12 version.
