Problem:

Filters by Attributes are not displayed.

Solution:

1- Go to WooCommerce → Status → Tools.

2- Click on the language switcher at the top of the screen and switch to the secondary language.

3- Look for the section to Regenerate the product attributes lookup table.

4- Search for the product you want to fix and click the Regenerate button.

Alternatively, you can disable that feature:

1- Go to WooCommerce → Settings → Products → Advanced.
2- Uncheck the Enable table usage option.
