Multi-lingual in static pages in customiser

Hi,

The theme that I am using is called Businessx. It assigns a page to be front page using the template selector. So far I have create three pages and the are all selected as front page. I have to change the contents of the front page using the wordpress customiser.

However, when I try to fill in my second language after the main language, the new contents that i have filled in replaced the ones that i had for the main language.

My question is, does polylang work with themes that relies on the customiser?

many thanks!
