Reply To: Shop filters not behaving correctly

Hello,

Try to install the classic widgets plugins on your site.
https://wordpress.org/plugins/classic-widgets/

Then try to regenerate “Regenerate the product attributes lookup table” in Woocommerce > Status > Tools: https://take.ms/LGpvf
In addition, please check Woocommerce > Settings > Product tab > Advanced tab and disable Use the product attributes lookup table for catalog filtering.

Let us know if the problem remains.

Best Regards.
