Hello,
I saw the screenshots you attached and visited your website. Basically the products page is controlled by WooCommerce and our theme doesn’t influence it. You can set the product columns to be displayed on the shop page from Theme Settings >> Shop >> Product Styles.
It will affect all the categories and shop pages. If you try and use the products by shortcode then it will also affect them. This is the part of default functionality and could not be overridden.
It requires customization and this is beyond our limitations and support policy.
Best Regards.
