Hello,
That sitemap doesn’t seem to be generated by the Rank Math plugin. Also, it seems it is being cached by the plugin Hummingbird.
Could you check your website to make sure you are using Rank Math for the sitemap and also to disable caching for the following pattern?
/(.*)sitemap(.*).xml
Looking forward to help you.
