Title in the Posts taged

Hello,

I would like to know why the title of a post is not displayed when this one is displayed passing by the word cloud.

——

Example:

This article is called “The Technical Documentation”
https://regulatoryandmore.com/2020/01/03/the-technical-documentation/

When we pass through the word cloud with the word “Technical File”, the title “The Technical Documentation” of the post disappears.

Thank you
