We have had some cases from other customers where the CSS generated from the Divi Builder was conflicting and when you change the text on one layout, it would affect the other layout  – this was only happening in the account area.

Solution: Please make sure you have not enabled the Divi builder on your account page (not the layouts but the account page where the WooCommerce shortcode is on). Having the Divi builder with a text module and the shortcode inside would add unnecessary DIV’s and cause conflict. You should not have any builder on the “My Account” page, use the builder in the layouts you specify in the library.
