Caption error in Mesocolumn theme

Dear Richie,

Thanks alot for providing your invaluable guidance to word press beginners like us. I am having issue whenever I am putting any caption below the images of my post. It gets left aligned by default after publishing. You can check its example at..http://www.traveliaa.com/ganga-in-rishikesh/

The caption gets left aligned and start with a ‘-‘. Can u please help me out of this problem? Thanks
