Hello,
Thank you for getting in touch and I am extremely sorry about the trouble this might have caused.
Rank math is adding the correct meta description if you check if your title/description is properly set up in the page source:

You can use this tool for the same as well: https://www.heymeta.com/
Do note that Google sometimes ignores the custom meta info altogether and show something from the page’s content. The best you can do is optimize your meta tags to try and match the intent of the search/keyword.
You can read more about it here

This section sheds light on that:
Why the search result title might differ from the page's <title> tag
Hope that helps. If you have any further question(s), please let us know.
