How to remove First-Entered Email Policy?

I was testing the Email Policy feature in the Control Panel, Mail Administration. Initially I was confused because there was no "Save" or "Update" button for this particular panel. Reading the Help, I finally realized I had to press [Enter] to save/create a new policy. Because I was testing, I used a temporary name for the test policy ("testme"). What I didn't realize was there would be no way to rename or remove the first policy entered, and it would become the new Default policy whenever a user is added or when a user is removed from another policy (instead of the general default "ZohoMail Business Policy").

If I create additional email policies, they all can be removed ('x' displays to right of each additional policy). However, after returning to Email Policy from other configuration panels, the initial "testme" policy entry doesn't have this & cannot be removed or renamed, (and looks rather unprofessional.) I don't have any users associated with the policy.

Is there anything I can do to remove or rename this "testme" email policy?
