Display switched to single column after update. will not switch back.

-- url of the page with the problem -- : www.redlineairsoft.com/index.php/parts-accessories

I just updated to Hika Shop 3.2.0

My products now display in a single vertical column.
Before the update they were in 3 vertical columns.

Nothing I do seems to affect the layout.
I am using Joomla 2.5.8
