Default bio is blank on Author template using CAA php code

We have added the CAA php code to our author.php template, however it is showing a blank profile. Code:
echo caa_get_current_author_bio();

Default bio working on this page: http://thrivenetmarketing.com/web-design/looking-for-a-good-website-hosting-service/
Blank on this author page: http://thrivenetmarketing.com/author/inzerillo/

Any ideas?
We are not using custom bios, but just want to use the plugin’s auto-generated bio from the default user profiles.

Thank you for your assistance and a wonderful plugin!
