Alert history not working

Hello guys,

I'm facing a strange problem.

There is a thing with some properties that have Alerts configured.

If I set manually some of these properties to "TRUE" the event of Alert works and the History populate normally.

On the other hand when i receive a message by MQTT, my property changes the value, the alert is set accordly, all the logic with this alert is working, but when i open the ThingWorxMonitor mashup, it displays my alert on the Alert Summary while it is active but it isn't poplating the Alert History, even when the alert goes down it doesn´t populate.

I'm currently using the same ThingTemplate to 10 differents things, only 4 of the 10 is working correctly.

Could you help me, please?

Thanks.
