Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Do you have any caching plugin on your site? If so, please exclude your sitemap URLs from being cached then do the following:
1. Head over to WordPress Dashboard > Settings > Permalinks
Hit the save button once.
2. Go to WordPress Dashboard > Rank Math > Sitemap Settings
Hit the save button once.
3. Head to your GSC and remove your submitted sitemaps then resubmit only the main sitemap(sitemap_index.xml)
That should fix the issue.
If it doesn’t, please do let us know so we can look at this further.
