hey some of my filter by option is not showing. i went to WooCommerce -> Status -> Tools and regenerate product lookup tables. Then it showed the filters for a few minutes and then again they disappeared. The only filter it continues to show is the brand and price
Only those filters show in the sidebar which is related to the products loaded on the shop or category pages. This is the default Woocommerce functionality. Please ask Woocommerce support to check and solve the issue because this is not the theme issue.
Also, I have found that you are using the old version of the theme. Please update the theme to the latest Woodmart 6.3.3 version and update all the theme plugins as well.
