CASB "Default_Dummy_Data_Profile" detections for DLP

[Andrew_Cooper]

We're in the process of tuning DLP policies and struggling to filter out a lot of detections for driver's licenses from non-US countries.  We've disabled all profiles that reference any of the non-US countries, but still seeing incidents detected for driver's licenses from non-US countries.  Today we configured Admin Alerts for Slack Pro and Business and connected the Slack channel.  We started see violation notifications in our channel for "Default_Dummy_Data_Profile" which is triggering on driver's license and passport info.  We never created this data profile, and cannot find any such profile, and the slack channel is also triggering on msteams instead of Slack.  Does anyone know what this "Default_Dummy_Data_Profile" is or how to disable/delete it.  Thanks
