Duplicate "Read more" link

Your slider is probably the best out there (and I think I've tried them all!) but whenever I activate it and use the shortcode, I get an extra "Read more" link with my slider. 

My site is http://tetabester.com

You can see the regular "read more" button beneath the excerpt but there's another one ("Leer más>") on the upper left corner.
Any ideas on how to make it go away?
