Catalog images superimposed – Atelier / Woocommerce

I have updated the latest versions of WordPress (4.4.1) and Woocommerce 2.5 in the past day. I don’t know if it’s related but tonight we noticed our product images on catalog and category pages were being superimposed, or not maintaining their spatial integrity, if you want to get wordy. Here is an example page: https://procrypto.net/product-category/men/mens-tees/

Any ideas?
Thanks!
