Filters not applying
it seems that problem could not be strictly relative our plugin, but due to recent version of WooCommerce. It seems to be related to the new attributes lookup tables introduced in 6.3.
You can find lot of topics about that on official WooCommerce forum on wordress.org, like this one.
We invite you regenerate this, go to WooCommerce -> Status -> Tools and click on:
- WooCommerce transients
- Product lookup tables
- Term counts
- Update database
- Regenerate the product attributes lookup table
- Clear Product Filter transients
- Clear Product Filter sessions
