Woo Widgets not displaying

I am currently using the latest version of WordPress and the latest version of wooCommerce.

I am using the twentyelven theme (well actually I’m using a slightly adjusted twentyeleven via a child theme) and I seem to be having a problems with the sidebars. Any of the woocommerce widgets in the sidebar don’t seem to work / display. Normal widgets seem to work fine it’s just a problem with the Woo widgets. I have tried pretty much all of them.

I haven’t made any coding changes to the core of the theme just simple css changes and such.

Any help would be gratefully appreciated. Thanks
