I took one of my cameras that has been working for years, and tested it with NON-movement (for a possible use).
With NON-Movement enabled, the Alerts 'On trigger' stop getting triggered. Unchecking NON-movement for regular motion, and the alerts get triggered.
The trigger tab and 'On Alerts' are correctly setup. They have been working all this time. It's when I enable 'NON-movement' that the alerts stop.
I must be missing something... or, is this a bug?
