Hello,

Yes, I mean to say that there is no option in theme settings to use the compare for other custom taxonomies.

You are using the 3rd party plugin for this new custom taxonomies so please ask the plugin author support for this issue or help because as you know the Envato support policy that we only give our dedicated support for the theme related issues not for the 3rd party plugins settings and configuration issues.

Thanks for understanding.

Best Regards.
