Google is not displaying the correct meta description tag of the URL. How t

A month ago I changed the meta tag of the following URL and I have been trying to increase traffic for it. I have resubmitted the URL in Webmastertool. However, URL index is very unstable, sometimes it loses index and this URL is showing the wrong Meta tag. I don't know where the error lies, currently I'm trying to share on social media. How to fix this problem? Hope to get help from you.
