qtranslate on variable product

I am using qtranslate on my website and it works perfectly for everything except for my product variations. I have 3 languages (en, fr and de) and when I add [:en], [:fr] or [:de] before the attributes, it works on the “backstore” of the product page, but not on the website. The first language appears correctly, but the 2 others just show the name of the attribute in english and “chose an option”. The options don’t appear, so I can’t add the product to the cart.

Can somedy help me please ? I have tried everything and look on many forums, but no one seems to know what to do.
