M2E Pro did not use New ASIN/ISBN Creation feature assigned because settings for ASIN/ISBN Search were specified in Listing Search Settings and a value "__" was set in Magento Attribute for that Product.

This warning appears to inform you that the New ASIN/ISBN creation functionality was disregarded because the Search Settings are enabled and the UPC/EAN value is provided. 


If your product is new and does not exist in Amazon Catalog yet, you can list it under a new ASIN and the Search Settings should be disabled. 


If this Product is presented in the Amazon Catalog, you should adjust Search Settings to find existing Amazon ASIN and list your product under the existing ASIN.
