Short description doesn't appear in Shop homepage

[Magev88]

Hello,
i have my Joomla 3.3 site with VM 3.0.4 installed here: www.idea-s.it/rocks
I have insert a .png clip inside the short description of some products (for now just one for testing), and if you see the VM product slide in the homepage clip is correctly visible while if you enter inside the VM Shop Homepage (here: http://www.idea-s.it/rocks/index.php/it/shop) short description disappear.

What can i do to resolve this issue? Thanks
