ALM, show only last active alarm

ALM, show only last active alarm

Hi all..

I use Windows IOT OS and zenon operator RT 8.20 for industrial PC with touch panel.
On specific Alarm message list screen (taken from PharmaHMI app set), I want to show only last active alarm, like on alarm status line.

But sometimes it happend that there all alarms deactivated, but in ALM last alarm stays as visible.
I think that problem is filter for alarm message list, which is set as:
1. Only current alarms
2. Historical data with max number of 3

How to define default filter for alarm message list?!

Attached is my settings in project AML.
