Hello,
Thank you for contacting us and we regret the inconvenience caused.
Assuming you’re referring to the snippet preview, since in most cases, Google uses the meta description as the description shown on the SERPs, the preview is generated based on the meta description that is added to the posts.
You can modify the meta description as per the requirement to get the preview.
Please have a look at this screencast for a quick reference:

Hope that helps.
Thank you.
