That doesn't look like a standard feature of XenForo. Is it from an add-on? If so, your best bet for assistance is posting in that add-on discussion thread.
Also, a link to the site you are requesting assistance for is usually suggested if you want timely assistance (or at least having it in your profile) so someone can go there and check (but this looks like it would be a specific requirement of being a registered user and an add-on in use, so usually making a test account for them to log in with would also be needed).
