WooCommerce Plugin issues with Ultimatum Theme

I’m building a site using Ultimatum and although I keep reading it’s supposed to integrate with WooCommerce my store and product pages aren’t using the theme layout like they are supposed to. Yet, pages like Cart and Checkout are successfully using the theme.
Please help with any suggestions:
