Hi,

I don’t think this is a bug.
Your “book” is a custom post type created by a plugin.
You need to edit breadcrumb function to work with your plugin, this is not covered in our support scope.
You can contact our developers for this customization https://theme4press.com/theme-customization-service/

Thank you
