Can't remove preset blog post icons

Hello,

I would like to remove the pre-installed blog posts but I don’t see the option when I go to edit it (I tried visual editor, backend and front end) They don’t show up when I go to the page in editor but they are there when I publish the post. http://www.roaminghippo.com/blog-masonry/ (I have one blog post and the the items I would like to remove are below it)

Thank you,

Angelo
