Compatibility with Divi Builder?

The plugin works like a charm, exactly what I needed, but when I want to style the checkout page with the Divi Builder, some functionality disappears. There’s no check on the requirement of the date/time selector, so customers who forget to select, can place their order without pickup date. Also, if you do select the date, it is not shown in the woocommerce order details.

Is there a work around for that?

Thank you
