Thanks for getting in touch with us.
1. First of all, I am assuming that you have already changed the SEO Meta Title and Meta Description with the help of Rank Math:
Add a Meta Description in Classic Editor:

Add title and description in Gutenberg:

2. Then, ensure that this is the setting in the Schema tab if Rich Snippets are enabled on your website:

To reiterate, the Schema title must show %seo_title% and the description should show %seo_description% – this will ensure your SEO title and SEO Description that you set up via Rank Math can also be used for your schema details:
3. The next step is to check if your title/description is properly set up in the page source:
