Hello,
Thank you for contacting us and bringing your concern to our attention.
This option is usually used to determine archive meta and will show depending on the theme you’re using. You can check this video tutorial as well: https://www.youtube.com/watch?v=TzDxO9FCstY&t=1797s
Regarding the Format Archives Robots Meta, if you enable this option, it will allow you to select custom robots meta for Post Formats Archive. If the content in the post format archive is unique and does not appear in other archives, then you can set “index” and “follow” in the robots meta. Otherwise, it is better to “nofollow” and “noindex” it.
Hope that helps and please don’t hesitate to let us know if you have any other questions.
Thank you.
