How to force Zabbix 3.2 to update events?

Question

Zabbix

There is Zabbix 3.2. In the Monitoring->Panel screen there is a window "Last 20 events". This window displays the results of the triggers. For example an Oracle event: "no space on tablespace -SYSTEM use 85%".
After the trigger fires, the value of 85% in reality may change to the worst value - 90%. But it will still show 85%. How to force zabbix to update value?

Answer 1

It would be desirable that the last critical value was really shown.
