Category Listing Page side bar widgets under listings

Something Ive been racking my brain over all day today. The widgets on the category listing pages are below the listings and not to the right of them like they should be. it seems to be specific to the listing page. I cant seem to find any open tags and didnt make any changes to the css code to make this happen. any thoughts on what it could be?
