Yes, Steve, this seems to be working, but instead of deleting ../wp-content/plugins/templates/card/card-single.php as you say above, the one I needed to remove was ../wp-content/plugins/templates/profile/card-single.php

Given that, I’m expecting that the folder is should move to plugins is ../wp-content/plugins/templates/profile/ — is that correct?

Thank you for your help, and I apologize if I was being obtuse at first.
