In the Odoo Online V18 database, I have an attribute "Size" with values 36, 37, 38, and I am trying to import products with the attribute "Pointure" with values 36, 37, 38, 39.

During the import, I get the following error:

"Multiple results were found for the value '36' in the field 'Product Attributes'", and the same error occurs for the other values.

I tested the import using the external ID of the attribute, but I have 600 rows, and each product has various values.

How can I correctly map my attributes with their values?

Thank you!
