Switch language not working from home

Hello,

Thank you for the theme, it’s great!

My website: https://curiouseveryday.com/
I am using the latest version of Activello. (1.1.1)

I am using polylang for internationalization. I have created a post in two languages and if I try to switch the language in the main page it doesn’t work, it reloads the page and the language is not changed is the same one as before (you can try it).
But if I go on a post and change the language from there it works!

Any ideas?

Thank you.
