We have hundreds of products that we need to remove attribute values from. These are not product variants, only product specs. We want to re-do them, so we need to delete them first. I've been trying to do it by importing them with empty values, but Odoo always throws an error telling me that an attribute line cannot have an empty value, which makes no sense because I can easily make it so by manually deleting the value on the product sheet.
How can we automate this or do it in bulk?
See the screenshot I posted in my reply below.
