Hello, @LambdaSP,
It is not showing on your site because you have not added the filters in the Shop Sidebar as I described above in my last reply, please read my last reply again carefully, once you will set it on your site desktop version, it will automatically show on mobile as well.
Otherwise, please share your site WP Admin URL and Credentials with me here in the private content area of this topic as listed below, so that I will check and help you out accordingly.
WP Admin URL:
WP Admin Username:
WP Admin Password:
