Buy it now button translation bug with transcy

[splan]

Hello, 

I'm using Transcy app to translate my store and I have the following issue:

When customer click on "Buy it now button" and go ahead to the checkout page for paying their orders, the store will revert back to the base language and not the chosen language.

Here is the link of my store: https://abstractionparis.com/en/products/here-we-belong-114

Can someone help regarding this problem ?

Have a nice day 🙂
