Loco translate in Zerif lite not working

Hi,
I tried using Loco Translate to do a multilingual page (ENG and FR), in the manage translations once I choose my theme, it is not showing my already customized page but the original virgin Zerif Lite theme.
How can I directly edit/translate my page and then have the two language mirror pages?
I’m really not good at computing, so any help will be super helpful!!
My page is : https://www.barakafilms.fr/

Thanks!!
