Event Registration turns to TEST transaction after clicking Map This Location

When on an active event registration summary page, if the user clicks "Map This Location" then clicks the Done button the registration is then turned to a TEST transaction. The message, in a yellow box, then states: "Test-drive Your Event Registration Page"

The URL has an added variable after leaving the map page: "&action=preview".

2) Click on Map this Location
3) Click Done
4) Click Sign Up
