VRM Notifier alarm issues

I have configured an Digital Input alarm on my Cerbo GX to monitor a ‘Gate failing to Close’ and set to notify after at 300 sec to allow time for gate to close automatically.

All tests ok, but i have two issues.

1 - Notification after 300 sec doesn’t work, notification comes through immediately.
2 - Removed the alarm rule from VRM Portal but still receiving the alarms

Can anyone assist
Thanks Geoff
