You have too much products (about 3000) that’s why ajax search cannot get the products by title for wpbakery elements. Try to raise these values – http://prntscr.com/tuxu45 , contact your hosting provider to get assistance with this. It may fix the problem, but without a guaranty, because the wpbakery builder just can’t parse the current amount of products via ajax.
Please note that you need to build content using only one builder, don’t try to edit page that was created by WPBakery using Elementor.
