Error with Facebook like button in Magento

Hi friends,

        I am developing a website in Magento cms. I downloaded & used extension for facebook (Facebook Connect and Like Free) with the help of Magento Connect Manager. After using it, I realized that it posts some irrelevant data (i.e css code & other html tags) as well. I don't know the reason behind it. Here is the code which I found on my facebook profile page :


<​p><​span style=“font-size: large; font-family: ‘comic sans ms’, sans-serif;”>Aam aadmi ke dreams…are made of these! <​/span><​br /><​span style=“font-family: ‘comic sans ms’, sans-serif; font-size: large;”><​/span><​/p> <​p><​span style="color: #ff9900;

        Can someone help me to figure out the exact reason behind it??
        I really appreciate your help. Thanks.
