[Plugin: WooCommerce Multilingual – run WooCommerce with WPML] problem with AJAX

In another language than the default language I set (Dutch) the “order review”/”shop table” isn’t translated on https://www.ehealthcigarette.eu/en/checkout/. However if you take a look at it and you refresh the page, you’ll see that when the table is updating the correct language is displayed, but when updated it changes back to Dutch. The same problem with payment methods, order button and error messages.

I think the problem is in AJAX in the plugin because when I downgrade to version 1.0 the translation is correct but then no live updating. The problem occurs from version 1.1.
