Posts on portfolio page display Open Graph meta tags

Hi everyone,

Posts on my portfolio page display Open Graph meta tags instead of the author’s name or the date. When I change the category that I want to appear on the portfolio page, posts of that new category then display Open Graph meta tags as well, but the posts of the old category go back to normal and don’t display the OG meta tags anymore.

How can I get rid of the OG meta tags in portfolio posts? It looks ugly…

Here is a link to one of the posts: http://www.skyriderfilms.com/coffee-talk-episode-3-dress/

Any help is appreciated!
