Article title is not visible

I use version 2.3.1 and J2.5.14.
In the search results click article title, and do not visible in the browser the article title.

What could be the problem?

Thanks in advance

This is not a CP issue. In fact Custom Properties lists search results. When you click the article title you go outside Custom Properties "jurisdiction".

To show/hide the article title in the browser title you need to edit the menu items parameters.
Here's a good thread I found on Joomla forum about the subject:
