As recommended by @mrtom414 in https://wordpress.org/support/topic/plugin-section-is-overlapping-text-in-page-creation/#post-11349802,
I tested it on Chrome, Opera and FireFox. Although all of them are updated, it only worked on FireFox.
So, I consider the issue partially solved.
This may be a plugin or theme conflict. Please disable all plugins except Yoast SEO, and use one of the default (Twenty*) themes. If the problem goes away, enable plugins one by one to identify the source of your troubles.
If you can install plugins, the Health Check & Troubleshooting plugin offers a troubleshooting mode that will disable all plugins and change the theme for you, while you’re still logged in, without affecting normal visitors to your site. Once in the troubleshooting mode, please activate only Yoast SEO and attempt to reproduce the issue you described.
If you are unfamiliar with checking for conflicts, we’d like to point you to a step-by-step guide that will walk you through the process: How to check for plugin conflicts
