Multiple choices of address for new customers

I'm getting a odd behavior when a customer signs up on the site.

They are getting confused with old customers and a france one.

Hi,

Would it be possible to have a link to your store and some credentials in order to test it ?
I think it will be useful to find in the database the entries for these three addresses ( table " hikashop_address ").
If we can see what's the "address_user_id", it could help us to understand.
You can make a search on the column "address_lastname", it will be easier.

Regards,
