CPT Archive index failure

Dear Rank Math devs,

on Google Search Console, since a month I am getting the error:

Submitted URL marked ‘noindex’

regarding the url this url.

The website was launched on 15th of July and initially I was not getting this error. But from 1st of August I get the error, till now.. In fact, going to that url and looking at the source code, I see a no-index. I followed your guide: link rank math guide but nothing worked.

That link is present in my sitemap as an archive of my CPT “lezione”. You can find it in: Sitemap and then in cpt sitemap

The archive is built like this: Gist Link

The single CPT Lezione are getting indexed, but not the archive page. I also tried to use:

add_filter( 'rank_math/frontend/robots', function( $robots ) {
  if ( is_post_type_archive( 'lezione' ) ) {
    $robots['index'] = 'index';
  }
  return $robots;
});

but it did not work.

For your reference, I created the CPT using this plugin.

Could you please help me solve the issue?

WP 5.8, Rank Math 1.0.70
