Yoast SEO settings unavailable in an archive page from wordpress plugin

  1. Yoast SEO can have limitations for archive pages. Try a different SEO plugin such as Rank Math perhaps.
    Your other option would be to open the archive.php file of your theme and add your custom code in there if required.
    You may also contact the developers of that podcasting plugin to see if they have a solution.

  2. That title is inserted through your theme. You can open the file archive.php and look for the insertion of headings. Change those headings in there but be aware that it will change on all archive pages/categories. For that reason it is advisable to modify it through your podcasting plugin.
