Since the Protestant and Catholic editions are the same product, except for variations in front matter, Faithlife provides unlocks for both when you buy one. This is to ensure links to these works in other resources will be live irrespective of which edition is referenced in the resource. I'm guessing you alresdy have one of the editions.
