Contributors are listed in the Free Designs section, though not in all cases in the actual zip file (some designs have this, some don't). As the design files were contributed by our generous users, and we did not create them, we don't really have much say as to the contents of the actual zip files.
If this does not resolve your issue, please feel free to send us an e-mail at support@annthegran.com. Our email support hours are Monday to Friday 9am to 5pm Eastern Standard Time, and Saturdays 10am - 6pm.
