CirrocumulusRick, enforcing those entities won't change the policy mode from transparent to blocking. Those entities will just be removed from Staging.
You can still learn and tune in transparent mode. Just ensure the blocking mask settings for the violations you are interested in have the Learn box checked. Then any violations will be identified in the Manual Traffic Learning section. Without having blocked any real traffic.
You should continue to monitor the manual traffic learning section until you're confident no more false positives are being seen, then you can look to turn the policy to Blocking mode.
Hope this helps,
