Translated strings in url (cart) not working since update to Virtuemart 3

[anna_w27]

Joomla Version: 3.4.1
Virtuemart Version: 3.0.6.4

I've updated today from Virtuemart / Joomla 2 to Virtuemart / Joomla 3.
Everything works perfectly except for a couple of translated URLS in Virtuemart.

In my shopping cart it is not possible to select shipment or payment (when I click on it, it refreshes the shopping cart page and doesn't redirect)
I use the Dutch translated strings.

When I disable "translate strings", everything works fine again.

Hope someone can help me!
