Thank you for contacting Rank Math and sorry for the inconvenience that might have been caused to that.
Can you try checking Schema tab if Rich Snippets are enabled on your site.

The Schema title must show %seo_title% and the description should show %seo_description%. This will ensure your SEO title and description that you set up can also be used for your schema details.
Then you can check if its properly setup from viewing your source. Or you can use this tool: https://www.heymeta.com/
If it matches then check if Google has seen the changes or not. To check when Google cache was updated follow this steps: https://i.rankmath.com/oJtcEm , click the arrow and click Cached. And see the date https://i.rankmath.com/F0BJIu
If the cache is from before adding the new title and description, then you just have to wait for Google to re-crawl and re-index the page with the new info.
Do note that if everything’s fine and Google still decides to show a different meta title/description for your search keyword, there is nothing you can do as Google sometimes ignores the custom meta info altogether and show something from the page’s content that matches the search intent better.
The best you can do is optimize your meta tags to try and match the intent of the search/keyword.
