TSP Accelerator missing email notification

Hello, 

I have deployed and activated several TSPs from TSP Accelerator. Some of them works with no issue, I can see that I have received email notification when rule was executed: 

For example for Monitor Internal Logins that Bypass SSO, Detect Privilege Escalation. 

However, for the following TSPs, I don't receive email notifications:  

Detect Login As Events - to test this rule I simply login as another user. 

Detect High Risk Data in List View, Detect High Risk Data in Report Export - I have email field configured for Account and Email in the Data Sensitivity Level as Confidential. And Confidential is marked as High-Risk in Data Sensitivity Picklist Values. To test it I create list view or Report (and do export) with Email field. 

Detect Report Exports by Unapproved Profiles - I have two profiles configured in Approved Profiles for Report Export metadata. I login as user with profile that is not in the list and create report and do export. 

I checked the configuration, metadata, confidential data settings, rules are activated, email notification configured to be sent to the expected user. 

I would appreciate any help to understand why the email notifications are not sent. 

Thank you
