Hello,
Thank you for contacting Rank Math today.
Can you please follow these steps?
1. Flush the Sitemap cache by following this video screencast:

2. Exclude the Sitemap files of the Rank Math plugin in your caching plugin. The cache could be via a plugin or from the server. For plugins or Cloudflare, please follow this article:

3. Clear your website’s cache and remove all the sitemaps from your Google Search Console account and submit only the main sitemap (your-domain.com/sitemap_index.xml).
Further, give Google some time to crawl your website and see if that fixes the issue.
If the issue persists, then please share the link to your website so that we can investigate this further.
Looking forward to helping you. Thank you.
