prestashop 1.7 mixed customer orders

[yourzed]

Hi, I have a fresh instalation on prestashop 1.7.

I'm having some orders that have same id_customer, but on the shipping address, it's from another customer.

Looking on the database, I see the table: cart, that has two diferent values: id_customer and id_guest.

On these mixed orders, if the id_customer and the id_guest are diferent (If I search the id_guest on the guest table). This is really strange and anoying. Does anyone knows how can I fix it, or what files I have to look where this values are stored?

Maybe it's a theme bug, but I don't think so.

 

Thanks in advance
