Hello,
Thank you for contacting Rank Math today.
Please check if your actual SEO title matches the one you have set using Rank Math.
You can confirm the same by opening the post and then following this image tutorial

Once the source is opened, search for the word <title> and you can confirm if the title is the same as you entered in the plugin.
If it matches as seen in the HTML source code there is nothing to worry about. Google sometimes does not honor your titles and displays them as per their will.
You can go through this post on Google Search Console support section.
Specifically, you might want to check the title Why the search result title might differ from the page's <title> tag
Thank you.
