Cant seem to get it to work

Hello. This plugin doesn’t seem to work for me. It is supposed to display my products in a set number of columns, right? I set it like this: http://i41.tinypic.com/2rooqgy.jpg for 4 columns
but I’m still getting one column on my shop products page: http://www.mol-innov.com/new/products-3/
Am I missing some other settings on this?

I’m using woocommerce 2.0.12 with yootheme “inspire”.
