In the section: Are product options supported? On this tutorial: https://support.shippingeasy.com/hc/en-us/articles/204437329-How-to-use-ShippingEasy-with-WooCommerce-v3-x-plugin

... where do I go in woocommerce to find this box that it speaks of? I've searched the web, looked through every option on my woocommerce, but I still can't find anything about a Display Product Options checkbox. Right now shipping easy isn't pulling my T-Shirt sizes over so we have to manually go back to our website to find the sizes before packing the shirts.

Any help would be huge!
