woocommerce product display errors

after optimizing my siste using huminbirds css minification tool my store is now displaying empty gaps or spaces in between the products on http://medsinroute.com/menu, it is also running all the center products together so they have no spacing.

I was unable to fix this by undoing any of the minification changes in the plugin settings but I know the problem is some formatting code in the css

I looked at other threads for similar issues and the fix was always something different
