Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
I’ve checked your sitemap, and it seems that it is already working fine.
Please remove all your submitted sitemaps and resubmit your main sitemap only /sitemap_index.xml then give Google some time to recrawl your site.
If the issue still persists, please also share the affected URL for this issue. Furthermore, you can check our guide to fix this issue in GSC:

I hope that helps.
Thank you, and please don’t hesitate to contact us anytime if you need further assistance with anything else.
