I don’t recommend going back to an older version, instead I suggest resolving thath with this custom code:
Add this custom code to the functions.php in your theme/child theme directory (copy from line 3 only!). Before editing, please make sure to have a full site back-up just in case!
Some WooCommerce attributes might be taxonomy terms, and others might be custom fields, it depends. On the Index table options panel, make sure to include any taxonomy that might be a product attribute: https://i.imgur.com/h2pazi8.png
