If an exclude suffix validators is added to a Data Identifier (DI) for and endpoint policy it will not exclude the detection properly if a trailing comma is present on the validator.
This is caused by the parser not properly handling the trailing command and invalidating the entire validator.
Release : 15.8
Component : Endpoint
This is a known issue and will be addressed in a future release.
Remove the trailing comma from the validator then apply it to the DI and save it. (Note that when you edit validators you must click the "Add Validator" button to update it before saving the DI)
