WooCommerce: Translation lost on AJAX call in Checkout page [closed]

Question

I'm using WooCommerce for a site that I'm currently working on. And I'm creating it for a language other than English. I do the translations by means of the .po file.

The issue that I'm encountering is in the Checkout page. There is a table of order review which upon page loaded seems to be refreshed by means of AJAX call. Before the call the texts are all translated. But after the call the texts all reverted back to their original language (ie. English).

How do I retain the translation after the AJAX call?
