Meta robots noindex not appearing

Hello,

i have my wordpress installation running the bbpress plugin.

In the Yoast seo plugin configuration i have the opportunity to noindex tags (topic-tag).

In the edit tags page I actually have every with the “noindex” setting properly configured.

The problem is that I dont get to have the robot metatag in the code of the tag page, for example in:

https://www.gruppomoney.it/forumgm/topic-tag/tempi-abf

I only see:

<!-- This site is optimized with the Yoast SEO plugin v5.8 - https://yoast.com/wordpress/plugins/seo/ -->
<meta property="og:locale" content="it_IT" />
<meta property="og:type" content="object" />
<meta property="og:site_name" content="Forum Gruppomoney" />
<meta name="twitter:card" content="summary" />
<script type='application/ld+json'>{"@context":"http:\/\/schema.org","@type":"WebSite","@id":"#website","url":"https:\/\/www.gruppomoney.it\/forumgm","name":"Forum Gruppomoney","potentialAction":{"@type":"SearchAction","target":"https:\/\/www.gruppomoney.it\/forumgm?s={search_term_string}","query-input":"required name=search_term_string"}}</script>
<!-- / Yoast SEO plugin. -->

and no reference to any “noindex” in the rest of the code of the page.

I checked different links like:

https://yoast.com/wordpress/plugins/seo/yoast-seo-robots-meta-configuration/

https://kb.yoast.com/kb/dont-see-index-follow-in-meta-robots-tag/

and some other threads but I didn’t find a solution.

Thank you very much,

The Process
