empty Addresses in the db table

-- HikaShop version -- : 2.6.4
-- Joomla version -- : 3.6.5

Hello
I was looking for something in the db and I saw that in the tabble address there are a lot of them more than the user.
I think that they are from tests that i made before, the strange is that they are empty.
My question now are
1)Why if I deleted test user I have still the adresses in the db and many of them empty
2) if they are not associeted to any user can I delete them?

I attache some screen to show you
Thanks
Frank

Hi,

1. Maybe a previous bug of HikaShop which didn't delete the address, or which added empty addresses when you imported data from another ecommerce extension, etc.
2. Yes, you can delete them. It shouldn't do anything.
