Delay Notifications settings

I have my Delay set to 2 hours on notifications of my temperature sensors not pinging. They tend to drop ping a few times a day and I was getting notifications on all of those (they aren’t critical). But even though I have it set to 2h…I get notified even if they are offline for just a minute or so so the alert clears but I still get notified. Is this a known issue or is it operator error and I have something set incorrectly?

Try changing the interval back to 5m.
