user registration via hikashop

Hi,

after upgrading to v1.5.8 i have some issue with user registration.
before upgrade, user was able to select if registration was for a company or personal.
based on the choice, hikashop user registration should display or not additional fields.

now, all fields are displayed and required.

to understand what i did i attached a screenshot and check my previous post ( www.hikashop.com/en/forum/4-how-to/35108...nies-and-people.html )
if user select "person" fields VAT, company name and trading chamber number should be hidden.

before it was working like that...

what's happened ?
thx

it's on my local computer so can't send a link

any idea where it could come from ?

especially because it was also working for me.
we already talked about it several month ago and everything was fine...i didn't change anything so i don't understand...

i did a fake new field just to check if something was wrong...but even on the new field it doesn't work.
if i select person instead of company, related fields are still visible

to make things clear:
- it works correctly with the popup window.
- it doesn't work wit onfly registration during checkout and also for standard user registration from hikashop
