New DIVI checkout modules issue?

Hi. Already submit a ticket but I know my 6 months support expired last year so I post here, too ( maybe it could be useful for others, too).

I think there is a problem with the new DIVI woocommerce modules and the Checkout Manager.

When you activate the DIVI builder in a checkout page, that page is converted into the new modules. Unfortunately, when the page makes the POST back to the server, CM added fields are not sent so that, if a field is mandatory, it will keep asking for it: of course I made a few tries using the Chrome dev toolbar to see the POST payload to.

Hope this helps
PS: I fixed my shop using the history feature for my checkout page and reverted it back to a previous version (without the new modules)
