Hello,
First of all, note that this part of the forum is in English only, sorry for this return.
Now, for your current issue, we think that you used the guest mode in your Login & Registration part (Configuration => Checkout tab)
The Guest mode allow HikaShop to create Customer with
only an Email, if you want to collect customer data, indeed the Guest isn't for you.
Always, in
Login & Registration part, you can force your customer to provide data with the option "
Ask address on registration" to
Yes.
Now in order to be more precise in our help, can you provide an
Url link in order to allow us to see your checkout process, please ?
Regards
