Not sure if it was intended design, or not. If I specify a taxonomy in the Taxons column, the product is added to every parent taxonomy instead of only the child.
E.g, product is added to
Health & Beauty > Personal Care > Cosmetics > Cosmetic Tools > Skin Care Tools > Foot Files
Health & Beauty > Personal Care > Cosmetics > Cosmetic Tools > Skin Care Tools
Health & Beauty > Personal Care > Cosmetics > Cosmetic Tools
... etc
