Hello,
Thank you for contacting Rank Math support, and sorry for any inconvenience that might have been caused due to that.
Can you please share the affected post URL with us so we can further check it on our end?
Looking forward to helping you on this one.
Hello,
Please navigate to WP Dashboard > Rank Math > Status & Tools > Database Tools and Delete Internal Links data. Once done, edit and update your posts to generate the new internal link data for the Link Counter.
If the issue persists, please edit the first post on this ticket and include your WordPress logins in the designated Sensitive Data section.
Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:
https://wordpress.org/plugins/temporary-login-without-password/
You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.
But what about external links. No one gave me backlinks. I know this because it was showing 25 external links at the time the post was in draft. What should I do about it?
Hello,
External links added to the content on your website are not the backlinks for your website.
After deleting the Internal Links data, the data for external links would also be deleted and would be calculated again when you’ll update the post.
Hope this helps.
Thank you.
Hello,
We are super happy that we could address your concern.
If you have another question in the future, please feel free to create a new forum topic, and it will be our pleasure to assist you again.
Thank you.
