Issues with language switcher

I’m facing an issue where I can’t seem to get the language switcher work properly.

I set it up so that the current language is hidden and there are only two languages so only the other language is shown. However, when you click on it the page is not redirected onto that language. This holds true with both settings: Detect browser language activated and deactivated (though slightly different behaviour). I also tried to change the default language of the browser from EN to IT and while it does work for some time, after a few clicks it seems to stop working and one cannot go back to the IT version.

You can see for yourself at https://www.lucentumrooms.it/ where I’ve left the Language Switcher visible though it’s not working.

The default language of the website is set to EN and currently the Detect browser language is active so that in the first instance the behaviour is what is expected (redirected to browser preferred language).

I paste down here the system info:
