VM "Add to cart" link points to English cart unless turning off Joomla SEO

[zczfwz]

Help guys,

I have this issue. My site is multilingual site with English and Chinese. I have followed the "Multilingual Joomla 2.5 Webinar" youtube video to setup my site.
But the problem is, when I click on "Add to Cart" button in Chinese product details page, VM will redirect me to the English shopping cart page.
I also found once I turned off the SEO in Joomla config, the Chinese shopping cart will show up, but I really need the SEO on my site.

Can anyone help me with it? I tried to figure out where the place in the code to redirect me, but seems it's not that easy for me.

Many thanks!

Environment:
Joomla! 2.5.9
VM version: 2.6.0
php version: 5.3.5
