The text field does not change

Dear Tom, no matter what I do with the current pro plugin, the text field “Call for Price” does not change when I change it in the backend. This was the sole purpose for me buying the unlimited sites PRO version. I would truly appreciate your help 🙂 I might be missing something here or this could be a bug. I’m using newest Divi theme and latest wordpress/woocommerce on a PHP 7.2 platform. Almost everything stock without much weight/plugins. Thanks!
