Alerting trigger stuck

[geostant]

I've created a new trigger for one of my host's item to set off when last value is bigger than 14
After setting this trigger up I noticed that the trigger wasn't high enough and the trigger set off immediately.

I've changed the trigger threshold to 50 but the trigger didn't cleared and it's still alerting on the dashboard,
setting ACK on that trigger didn't helped.

Is it a bug or something that I'm not doing right ?


Thanks

Hello, geostant!

Items must be in supported state. Can you please recheck the state of all items involved in trigger? Do they retrieve any values according to the interval configured?

Are you using last() function in trigger expression or something else?
