Refinement breadcrumbs on WP

1. In the parent link of the breadcrumbs need to configure the recognition shortcode plugin for the city.
2. In the target path for the current page which duplicates need H1 at the end opposite to drop the shortcode with the city.
3. Configure the correct rel canonical for the generated pages by city. Now some of URL of cities is formed incorrectly.
4. When switching to the normal styles of bread crumbs, of course, the item disappears. You need to fix.
