Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
I have checked the sitemaps and they seem fine, in fact, they are working in the validator (https://www.xml-sitemaps.com/validate-xml-sitemap.html). If you want, share a screenshot (you can upload the image to http://ibb.co/ and share in the Sensitive Data section the URL) showing us what is off and we will be happy to help you.
Looking forward to helping you. Thank you.
