200+ attribute values are auto-populated when I add the Manufacturer attribute (Odoo 18)

Question

How can I stop Odoo from auto-populating attribute values after I add an attribute to a product?
I am using a Manufacturer and a Brand attribute so that my customers can use this as a filter in the shop and also see the information on the product page. Display type is "Select", Variant Creation is "Never", and Filter Visibility is "Visible". All is good on the front end.
When I create a new product and add the Manufacturer attribute, all 200 possible values are auto-populated. I need to delete 1

Hello Jean-Sebastien

Solution would be Automation action on product.template.attribute.line model, to reset value of attribute value on selection of attribute.

*1) Activate Developer mode from setting --> Click on Activate Developer Mode.
