Hierarchical %taxonomy%/$post_type%/ not working properly

Hello,
I recently had to convert a single language website (italian) to a double language one.
I work with QTranslateX and Qtranslate Slug.
My permalink structure for a specific custom post type (products) is set to be hierarchical in this way:

$args = array(
			'labels' => $labels,
			'hierarchical' => false,
			'public' => true,
			'show_ui' => true,
			'show_in_menu' => true,
			'supports' => array('title','editor','thumbnail'),
			'menu_position' => 21,
			'menu_icon'   => 'dashicons-media-spreadsheet',
			'show_in_nav_menus' => true,
			'publicly_queryable' => true,
			'exclude_from_search' => false,
			'has_archive' => false,
			'rewrite' => array('slug' => 'catalogue/%product_cat%','with_front' => false),
			'query_var' => true,
			'can_export' => true,
			'capability_type' => 'post'
		); 

Where %product_cat% is a custom taxonomy.
Now permalinks are badly generated
https://www.arredoufficio.com/catalogo/%cat_prodotto%/reception-per-ufficio/
instead of being
https://www.arredoufficio.com/catalogo/reception-per-uffici/reception-per-ufficio/
The slug are working properly but the permalinks frontend and backend are not.
Evean yoast sitemap reports bad permalinks.
Did anyone have the same problem?
Any ideas?
Thanks in advance
