More importantly, you should simply fix it. As either you have a canonical problem where Google is recognizing the same page as two separate pages because you don't provide a canonical page. Or you simply have the same Title and/or description on two separate pages. Either way they are easy fixes that Google WMT usually recognizes within a month of being fixed.
