Offline units not displaying in Explorer

Hi all,

In recent months I’ve noticed that I’m not getting alerts for Host not reporting.

The condition is set up and active but any unit that goes offline does the following:

List view - the site greys out, which is the same thing that would happen in the event there was no active alert policy.

Navigator view - the site disappears from the view completely.

Essentially I’m getting the correct visualisations for my other conditions/policies but not ‘host not reporting’.

To confirm the alerts are still coming through the events log so I have it there, but ultimately would like it back visualised like it was before.

Has anyone else come across this?
