WooCommerce with Boldgrid category image resizing not working

Hi - I am using WooCommerce with Boldgrid. It all works well except for the category page. The images on there won't resize. I can resize them with WooCommerce, and when I view the image alone it has been resized, but on the category page it stays the same size (although blurry). I tried viewing the site with TwentyFifteen theme and the images were the correct size, so it has something to do with the BoldGrid theme. I tried using some css that I found in other support forums but it did not help. Thanks.
