Linkedin social button not linking correctly

In Highend Options>social links i enter in the URL for my linked in profile, then selected the icon from the ‘choose and order’ social networks box. however, my linkedin button/icon is adding my homepage to the URL so the link is broken. for example, my Linked in url is: http://www.linkedin.com/in/drsmartphones, but when i click the icon in the header on the live page, it looks like this: http://www.drsmartphonesdallas.com/home/www.linkedin.com/in/drsmartphones

please help.
