Page Permalink issue

Hi,

I use WordPress 5.0.2 – Theme Enfold 4.5.2

In a page, before this last version of WordPress, it was possible to change the permalink of the page under the title.

Now, with the last version of WordPress, there is a Permalink box on the right. But in this box, i just can see the permalink preview, there is no url box where i can change the url.

Someone knows this problem?

Many thanks
