Column layout in category view

I have a new site up and running and would like to see if I can get the categories to display in columns rather than rows.

I have installed the mod and can see the option to change between column and row but when I select the column layout and set it to 3, it still only shows 1 column when you loot at any of the categories.

The site is www.valleygiftsandkeepsakes.com

Thanks
