I updated my attribute’s name and slug and now the woodmart layered nav is not showing up on my shop page. The issue is the same as this post here but I could not get it to work after trying what @crazysport168 did.
I have also tried clearing all my cache – backend, purging on admin and clearing browser.
If it does not work, try please check Woocommerce > Settings > Product tab > Advanced tab and disable Use the product attributes lookup table for catalog filtering.
