I have a question about related fields in Odoo. In version 17, I could add fields from my sales order to my accounting invoices without any issues.

However, in Odoo 18, following the same steps, it "works," but I noticed that only the last generated value is overwritten in all records. Previously, each invoice kept its corresponding value from the sales order, but now all records update with the last generated one.

Do you know if there is a solution for this?
