Cloned published post not displayed in Rankmath SEO sitemap.

I'm having some trouble with Rank Math SEO. I recently cloned a bunch of posts on my WordPress site and published them, but none of the cloned posts are showing up in the sitemap generated by Rank Math.

Here’s what I’ve tried so far:

• Verified Post Status: Cloned posts are published and not drafts or scheduled.
• Checked Sitemap Settings: All relevant post types are enabled in the Rank Math sitemap settings.
• Regenerated Sitemap: I’ve clicked ‘Save Changes’ to update the sitemap.
• Cleared Cache: Both site and plugin caches have been cleared.
