ShopEngine Archive (Search) Page no Longer Responsive

Before the last update of the ShopEngine plugin, only one product was displayed per row on the mobile breakpoint. However, after the update, 4 products are now being displayed on mobile. I use the Hello Elementor theme. And even after I changed the number of rows to X in Appearance->Customize->Woocommerce->Product Catalog, nothing changes on the mobile breakpoint. Your assistance will be highly appreciated. Thanks in advance.
