I’m working with new version, you can download it tomorrow. It will have an option to disable wishlist feature from customize panel.
Anyway if you need to solve it immediately, you can follow the steps.
open new-shop-pro/inc/newshop-woocommerce-functions.php file.
remove the below code on line 241. add_action( 'woocommerce_before_shop_loop_item_title', 'new_shop_pro_display_yith_wishlist_loop', 97 );
It will work. Please update me if it works for you.
