Likely a theme issue with messed up or outdated templates.
Try temporarily switching back to the WordPress Twenty Sixteen Theme, or Storefront, and disable all plugins except for WooCommerce. If that resolves the issue, then slowly re-enable features until you find the one that’s causing the conflict.
Thank you for your answer. I change the theme and deactivated all plugins except WooCommerce. Unfortunately to problems still happens.

Do you have an other idea?
Do you have the cart shortcode entered twice on that page? That’s what it looks like is happening.
Hmm i can’t find a dublicated shortcode on that page. It’s strang that it fix the problem if i refresh the page. Do you have an other idea?
Edit the page, click on the “text” tab, and then screenshot the page for me like this: http://cld.wthms.co/Pifi/2Y3akkpJ. Then post a link to the screenshot here.
Do this while all other plugins are deactivated except for WooCommerce, and while using a default WordPress theme.
Thank you for your help. I found the problem by my self. The reason was the visual composer. I hidded a cart element for some divices, unfortunately it doesn’t work.
