In Simple Feature Requests, request titles in the archive are output with an h2 tag. Single request titles are output with an h1 tag. Sometimes, due to your theme or other circumstances, these heading tags are not appropriate.
To change them, go to Requests > Settings > General in the WordPress admin panel.
Under the ‘Setup’ section, you’ll find two settings: ‘Single Request Title Tag’ and ‘Archive Request Title Tag.’
You can choose the appropriate HTML tag for each type of title and ensure your site’s SEO and readability aren’t negatively impacted by an improper hierarchy.
From your documentation: There are no such options in settings.
