Issue happens if the application filter exists with the exact same name 'DLP App Exclusion Filter' in the Application Filters configuration. The filter might be renamed or removed.

If the filter does not exist, A filter need to be created  with the exact same name. Also  'shared' check box in the application filter setting needs to be checked, so that the filter is accessible across all device groups.
