Checkout adress same adress input not showing

-- url of the page with the problem -- : www.lacestamagica.com
-- HikaShop version -- : 2.3

-- PHP version -- : x.x.x
-- Browser(s) name and version -- : XXXXX x.x.x
-- Error-message(debug-mod must be tuned on) -- : Error_message

I have a problem with address in checkout, i selected the full display and select to display the same address check, but its not displayed.

I think this option should be brought back. I like the new style but the people is very lazy...

I know i can use the old style, but this is about improving the extension and it´s a funtionality every platform has displaying it as the new models are.

The option that the shipping address is the same as the billing address only works when selecting 'pop-up for the Adress'.
When is the update planned that this option is also going to work with the other (AJAXi) options?

My clients would love to see this!

Thanks !
