Hello @riyazmuhammad,
We’ve checked the URLs from your screenshot, and indeed duplicate URLs are appearing.
For troubleshooting, please follow these steps to flush your sitemap cache:
1. Flush the Sitemap cache by following this video screencast:

2. Exclude the Sitemap files of the Rank Math plugin in your caching plugin. The cache could be via a plugin or from the server. For plugins or Cloudflare, please follow this article:

3. Disable the transient cache for the sitemap by applying this filter. This will make sure that your XML sitemap always reflects the latest changes on your site:
/** * Filter if XML sitemap transient cache is enabled. * * @param boolean $unsigned Enable cache or not, defaults to true */add_filter( 'rank_math/sitemap/enable_caching', '__return_false');If you’re not sure how to add this code, you can follow this guide:

Let us know how this goes.
