CSS code visible when shortcode is used

Hello there,

I can see a plain CSS code when SporsPress shortcode is used on a page:

http://beatheme.com/demo/–1dev/test/

Some themes display the code some don’t. Can you advise or point me to what can cause this issue?

Note: the code is always visible, when the wp_debug is enabled or disabled.

Thank you

Daniel
