Prices have disappeared from WooCommerce

I recently upgraded this site to WooCommerce 2.6.4 and the prices (which used to be there) have stopped displaying on the shop main page
http://www.thewhiskybarrelco.com/shop/
and the category pages e.g.
http://www.thewhiskybarrelco.com/product-category/distillery-drinking-sets/
Prices are OK on product pages but client needs them earlier than that, can you advise?
Thanks,
Steve
