Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for the delay and for any inconvenience this issue may have caused you.
Could you please provide the affected URL/s to check?
However, since you mentioned that they are already indexed, please try removing all your submitted sitemaps in your Google Search Console and resubmit your main sitemap only /sitemap_index.xml then give Google some time to recrawl your site.
I hope that helps.
Thank you.
