Avatar not showing in blog directory

http://myreclaimed.com/blogs/

As you can see, all of the blogs on the list have avatars what are uploaded. But the default is shown twice and the other one is black. But when I look in the users backend options you can see the avatar.

Permissions are set right and I uploaded the .htaccess file

This is how its called out in the blogs-directory plugin file, is this correct?
