Same page has 2 different URLs

Hi guys,

I’m using this rule for a custom post type:

add_action( 'init', 'rewrite_glossary_permalinks' );

function rewrite_glossary_permalinks() {

	register_post_type( 'glossary',
	    array(
	    	'label' => 'Glossary',
	        'public' => true,
	        'has_archive' => false,
	        'show_in_menu' => 'cmtt_menu_options',
	        'show_in_rest' => true,
	        'rest_base' => 'glossary',
	        'rewrite' => array(
	            "with_front" => true,
	            'slug' => 'guides'
	        ),
	        'cptp_permalink_structure' => '/%glossary-categories%/%postname%'
	    )
	);

}

If I set an initial taxonomy value for the %glossary-categories% and then I change that to a new one, I will end up having 2 URLs for the same post. Both URLs are working and pointing to the same post, but I only need one to work (the latter).

Example:
http://www.websitename.com/guides/parent_category/child_1_category/postname
http://www.websitename.com/guides/parent_category/child_2_category/postname

I have updated the permalinks (cleared transients), etc. But it seems nothing has any effect on this.

Do you have any suggestions?
