face share link displays subdomain's details

Dont know if this have been answered before. Whenever sombody clicks the like button on a page on my site, facebook displays the wrong details but directs to the correct page. It displays the meta info of the subdomain that we use when we direct to the mobile version of the site. How do I get facebook to display the correct title, description and image in the share link?

Yo开发者_StackOverflowur help will be much appreciated.
