BUG in Hreflang html tag and language switcher widget

[Overflow992]

I tried to edit the category base slug field using the following code:

add_filter( 'pll_translated_taxonomy_rewrite_slugs', function( $taxonomy_translated_slugs ) 
{
    $taxonomy_translated_slugs = array(

        // tax_name
        'category' => array(
            'it' => 'categoria',
            'en' => 'category',
        )

    );

    return $taxonomy_translated_slugs;
});

I updated the Permalinks and it seems that now when I change the language the slug in the url changes.

I noticed though that in the HTML code the HREFLANG tags have a problem, not showing the correct URL.

the correct URLs are:

IT: Mydomain.com/categoria/xxxxxxx

EN: Mydomain.com/en/category/yyyyyy

going to see the HREFLANG tags in the html code I find myself instead:

<link rel = "alternate" href = "Mydomain.com/xxxxxxx" hreflang = "it" />
<link rel = "alternate" href = "Mydomain.com/en/yyyyyy" hreflang = "en" />

So the slugs "category" and "category" are eliminated.

The links in the language switcher widget of Polylang also have the same problem.

Why not also update these elements?
