Create alerts in Sophos Central using sophostest.com

I am developing an integration with Sophos EDR and need to create alerts in Sophos Central.  

I have been using https://sophostest.com and downloading EICAR-PUA-Test and EICAR-AV-Test files and they had created alerts in the past for me.  Currently, the Threats are cleaned up and not creating alerts.  Is there some Threat Protection policy that I can turn on/off so that the alert is always created?

Thanks for any insight.
