We have added site categories and then gone through all 74 sites and assigned them to a category.
Site Categories page from main site: http://screencast.com/t/woPHdmjMNqhR as you can see all the counts are 0.
Category Listing page looks like: http://screencast.com/t/TlhWqeMBbu
On a sub-site: http://screencast.com/t/JGFW7TmKkJR
Any ideas what we are doing wrong?
