Bug in the filtering section for products

I noticed in the new version if i go to my product section of one of the sites in my muti-site setup and choose the orderby filter (ie name, price, ect) it will display no results (even though there are products.

for instance this url:

will display 0 results.

Is this a bug or am I doing something wrong? If this is a bug, I need to get some more forum points because I seem to be a bug finder!
