Note: First check if the incorrectly sorted size is compliant with Amazon's Valid Values (attached). If not, simply update the size with the compliant value and upload as an Update. If compliant, follow below steps:


  1. Delete the Parent SKU
  2. Change Product IDs from UPC to ASIN
  3. Select all sizes and format as text
  4. Delete age range description field (?)
  5. Arrange size map in order (?)
  6. “Update” for all SKUs
  7. Upload file after 24 hours
