Hello, @Giuseppe,
Please check the screenshot of your site, when I checked your site on my device after clearing the cache: https://postimg.cc/0Kzb1jRZ as you can see it appears just fine.
After I clear the cache from the plugin settings see here: https://postimg.cc/rKqPj4TS
Once clear the cache from the plugin settings and check back to your site I hope you will never face any issues.
Please watch this video I have captured for you: https://streamable.com/q5pm54
