Download Insight Exceptions - Does not seem to be excepting folder

We recently pushed out 12.1.4 to a subset of our user community and have been recieving false positives from download insight.  I am waiting for the team responsible for the application to get it to symantec but in the meantime we have been adding exceptions to the list.  However we continue to see risk detections on one folder that was added to the exceptions using a variable.  The folder is \users\%user%\appdata\local\assembly\dl3.  I've added using both [common_appdata] and %userprofile% for the users\%user% portion but we continue to see this folder detected for individual users.
