By configuring different Gift Cards, it is verified that their functionality is very limited, as different gift cards with different settings that should generate different account entries, are useless, because whenever someone uses a gift card to pay, always the "template" Gift Card of the system is applied.

How to configure Odoo to use the correct Gift Card and not the template?

(Odoo always apply this "Template" Gift Card to process payments)

What also creates some confusion is that the "template gift card" used for payment must be of product type Service to work and the Gift Card that "can be sold" must be of product type "Gift Card".
