You are right the Slug is the problem, the name is right but the slug has this repetition. So the problem is the import process?

Sorry, I don’t understand your question. I’m importing cars with wp-all-import and setting hierarchic taxonomy with the plugin. In the admin page of the single blog post in the taxonomy box I find:
– km0
— audi
— A3 sportback etron
But permalink results: auto/km0/audi-km0-2/a3-sportback-e-tron-audi-km0-2

How can I verify your question?
Thank you!

Hi, thank you for your answer, the problem is that I have added a Simple Product, not a Variable, and it gives me this error.
