Shortcode is Breaking My Blog

Hello,

I would love to try Blog Designer because it’s very beautiful and seems to be the best one out there. Unfortunately, when I enter the shortcode into my blog page, or blog posts, or both, it seems to break my blog page. I’m contacted my theme support and they said it would be best to contact plugin support. Here is what happens to my website http://www.plentyfit.com/blog-2/ when I add the short code.

Please let me know how I can use Blog Designer successfully. Thank you.
