Woocommerce product dimensions not showing on first product

I am using Wordpress with Woocommerce and would like the shop and archive pages to show the product dimensions along with the price and title of the product.

I added this code to my content-product.php woocommerce file: http://ift.tt/1Kyj7dt

Which worked great! Except for the first product in the shop loop. Both on the shop page and in other product lists, the dimensions are not shown on the first product.

How might I resolve this?
