When I try to sell something through POS and select a customer, Odoo always fills the Customer with "Simplified invoice partner".

This happens when selected any payment method and any quantity.

This change happens when I push the button "VALIDATE".

This problem cause we cannot make "list" or analysis about sales associated to customers.

Thanks in advance,

PD: Using Odoo 17.0e+ Enterprise edition. Tested on other database recently created and the problem persist. It seems to be an Odoo problem.
