Missing password field on registration page when switch is active

-- url of the page with the problem -- : davide-strati.it/zoeshop/
-- HikaShop version -- : Business 4.4.0
-- Joomla version -- : Joomla! 3.9.22 Stable
-- PHP version -- : 7.3.23

Hello.
Here is the problem:
as i select the registration with the switch, the password field is missing in the registration page, therefore it's not possible to complete the process.
This problem does not affect the cart page, where the password field is shown.

registration page:
davide-strati.it/zoeshop/index.php/it/registrati
cart page
davide-strati.it/zoeshop/index.php/it/carrello

At the moment I've activated the "all-in-one" solution for the live site and there are no problems; password field is shown in both pages; but I really like the switcher, so, even it's not a big issue, I would like to understand why it's happening.

Thank you.
Davide

Hi Nicolas.
I've already made that check and various combinations too, trying to figuring out the problem, so I've noted that as you select the switcher it clears the previous settings.
Look at the attachments: the problem is only related to the registration page, while on the cart everyhting seems to work perfectly.
So I've checked the menu item and the Hika Registration plugin; the item ID in the registration plugin is correct.
Looking at the codes there's no display:none properties that could hide the password fields.

As said before, there's no hurry. Have a good weekend.
