[Theme: Mystile] Woocommerce: Items section

Dear WordPress lovers:),

I have a little problem with my woocommerce webshop.

The connexcion between the theme Mystile and woocommerce works perfectly.
There is only a small problem.

if i select a product for in the shop card.
Then the card must change in price and 1 items, right?

My card put everything back together.

For example: 5 items cost 75 dollar.
if you select it in the shop than woocomerce put’s in in de shopcard, on the top. ( you can see it here: theme website : https://demo2.woothemes.com/mystile/shop/baseball-t/

On my site woocommerce make $755, the whole items section is lost.
i have made a screenshot you can check it here: Woocommerce card fault

Can somebody help me :)?

Thanks.

Job.
