Billing address missing after registration

I have just tested the site on a couple of PC's running windows and I registered as new users each time. After filling in the details to register I got the email and clicked through from the link in the activation email - when I did this the billing address was empty with only the new button showing - I had to re-enter the details again.

This was working fine - before I upgraded to essential and before I had issues with the shipping options.

Any ideas why it is not being pulled through.

Many thanks in advance.

That's a problem we were able to reproduce on our demo website.
We need to look at that and fix the problem.

Please edit the file administrator/components/com_hikashop/classes/user.php and change the line:
if(empty($addressData)){

to:
if(!empty($addressData)){

That will save the user address when the user register and solve the problem.
