If the attributes of a variation are not imported (i.e. one attribute appears as “any”), maybe they were global attributes and the names from your CSV don’t match with the existing global attribute options.
For example, your CSV might contain a color “dark blue” and the existing attributes on WordPress might be “Dark blue”.
You have 2 options:
- Make sure you import using the exact same attribute name
- Or import using the attribute slug in the variation row instead of attribute name
