I get a "Policy Duplicates" error when adding new policies using Endpoint Policy Manager Admin Templates Manager. What should I do?

When you try to use Netwrix Endpoint Policy Manager (formerly PolicyPak) Admin Templates Manager to "ADD NEW POLICY" under the computer or user Endpoint Policy Manager Administrative

Templates manager, you might an error expressing "policy duplicates."

Like what is seen here. This can happen when Microsoft's own ADMX definitions conflict, and two (or more) ADMX files share the same overlapping value.

Option 1 is to ignore the message and move on; it should work just find.

Option 2 is to clean up the underlying issue in your Central (or Local) store. Here's a Microsoft article on that: https://support.microsoft.com/en-us/help/3077013/-microsoft-policies-sensors-windowslocationprovider-is-already-defined
