@Mindlesswizard, Thank's for your input. However, we do not think that the links in the footer area (as shown in your printscreen image) might cause this issue, since we put the footer to every page in our site. Therefore, it should also affecting all the generated pages we have here (CMIIW) / not limited to the issue of duplicating content in User Profile page only as we asked.
Or maybe you have better explanation for this ?
