Adding product with variations in Amazon XML

Question

When I open this product in amazon I have message "This SKU has an inconsistent product classification with the ASIN. Please submit a feed to update this SKU to match the ASIN product classification."

What is wrong here, and does anyone can help me, because I can't find solution few days? I tried like in example under this text.

  $fileContent = '<?xml version="1.0" encoding="utf-8" ?>
