iMonitor Active Conditions messages do not disappear

Hi All,

I am using IDX 4.1.3.3 - 21.0.3.3

Normally the messages/alarms do disappear on "Active Conditions" section once the alarm clears or a new relevant alarm pops up.
But, it doesn't with this new version of iMonitor.

So, 100's of messages remains, which makes the monitoring of the network nearly impossible.

Any solutions highly appreciated.
