It seems to be a conflict between the Elementor PRO plugin and WooCommerce. We have already checked and it doesn’t work also with a default Storefront WooCommerce theme. You need to contact Elementor PRO developers for help on this matter.
Let us know if have any further questions.
You can deactivate the AJAX add to cart option in Theme Settings -> Single product -> Add to cart. Also, turn off the shopping cart widget in WoodMart -> Header builder -> edit header -> edit cart element.
