Alexa Integration - ESPHome Alarm Control Panel away mode not working

Hi Everyone,
i’m facing a strange issue where i’m not able to make Alexa Integration working as expected with my custom Alarm System based on ESPHome (Template alarm control panel).
Problem is that i’m not able to trigger ARM_AWAY state with any of the suggested phrases (i’m using IT-it locale).(ARM_HOME and DISARM are working well)
I’ve followed the integration guide, skill is in place, account is linked, device are recognized.
This is the relevant JSON section of the discovery triggered from the AWS lambda:

          ]
        },

My suspect is that the Italian utterance is not recognized as expected but i’m not sure…
do you have any clue on how to deeply troubleshoot or solve this annoying problem?
Thank you!!
