Zabbix trigger value not updated when already triggered

[Alwaysin]

Hello,

I have an item with a flexible interval that checks every day at given time, the trigger has fired yesterday and is still fired today, but the value has not been updated with the new value of today, it stays with the old value.
In latest data I see the correct value. How can I tell the triggers to update with latest value as they come even when the trigger stays fired? I use {ITEM.LASTVALUE}

Thanks!
