Hello,
I’ll try my best to understand your query, and please correct me if I’ve misunderstood it.
As per my understanding, you are talking about, the metadata (description) of your posts are not showing exactly how you updated them on search engines ?
If that is the case, please follow the steps below:
1. Please check if your title/description is correctly set in the page source using this tool: https://www.heymeta.com/
2. If it matches your settings, then you must check if Google has seen the changes already or not.
To do so, please check when the Google cache was updated for that page.
Here is a screencast that can help you understand how to check the cache date:

In case the cache date is from before making the changes in the snippet, then please be patient and wait for Google to re-crawl and reindex the pages with the updated information.
In case the cache date is from after making the changes, then there is no further action required from your end.
Please note, if everything’s fine and Google still decides to show a different meta title/description for your searched term, there is nothing you can do, as Google sometimes ignores the custom meta information altogether and shows something from the page’s content that matches the search intent better.
Here is an article, that might come in handy to understand this better:

We hope this information helps. Looking forward to helping you further.
Thank you.
