Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
This issue is because Google has not crawled your website after you made the changes.
I have checked the last cached date of your page and it shows 21 Dec 2020.
Here is the screenshot: https://i.rankmath.com/Hi9qPW
You can wait for Google to crawl your site or submit the URL manually in the search console. Once the URL is successfully crawled, you will be able to see the changes in the google search.
I hope this helps. Looking forward to helping you.
Thank you.
