1) WOOF. Can we get access (Dashboard + FTP) to your staging site to test and check the issue? We can’t reproduce this issue on our test installation, so need to check your site.
2) WooCommerce Product Filter.
a) we need to check your site staging site + access to find out why it does not work with custom taxonomy
b) If you have questions mentioned in google doc we would recommend you to submit the ticket on plugin support forum because our theme does not have options for this.
