I had to add a code in last time or something, but I have no clue what it was..I went ahead and made an account on your site. That second avatar is a duplicate from your user login bar. You have the entire thing showing in your HTML twice.
Your site has many customizations. You CLEARLY made a mistake in one of your many edits. Revert each template one at a time until you find the error.
This is not an issue with Flexile nor XenPorta. It is due to something you did on your site.
