Hello,
Thank you for contacting Rank Math and bringing your concern to our attention.
If your sitemap is opening fine with /sitemap_index.xml and /sitemap.xml, then you won’t need to follow the instructions displayed at the top.
You can also click the ‘I already added’ button at the right if you want to remove it.
Hope that helps.
