The default setting for the taxonomies(location, types etc.) in the info bar is to link to the default WordPress taxonomy page/URL.
If you want to stay on the same page and just filter the page’s jobs, add this filter to your functions file
add_filter('matador_get_the_job_meta_taxonomy_args',function (){return array( 'link_method' => 'filter' );});
you can also set this to return just the slug with no link
