Featured content Ashe demo

Hello! I'm using ashe demo Theme and I have some problems with featured content: FIRSt of all, I have added featured content from the dashborad but when I insert the shortcode [featured_content display_types=true display_tags=false include_type=grooming-tips,best-kitties columns=2 showposts=10 orderby=title] to a page, it say to me "Your Featured Content Archive currently has no entries. You can start creating them on your dashboard". why?? Then, when I add featured links, they appear on my home page, but the imagines are totally black! Thank you so much, my website is fabiolabeauty.it
