seeing in robots “content=”noindex, follow, …”. Why ‘noindex’?

I’m using Yoast to index pages but don’t understand why I’m seeing this:
‘<meta name=”robots” content=”noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1″ />’

I should be seeing ‘content=”index, follow…’ but don’t understand why it says ‘noindex’.

I checked the robots.txt:
User-agent: *
Disallow: /wp-admin/
Allow: /wp-admin/admin-ajax.php

I checked the Page settings and it is set to be indexed/followed.

So why the ‘noindex’?

BTW, when I disable the Yoast plugin, I see “<meta name=’robots’ content=’index,follow’ />” Seems odd to see the opposite when the plugin is enabled.
