Hi,
First, I recommend you to deactivate the "bootstrap design" in your HikaShop configuration because your template is not compatible with Bootstrap 2 ; otherwise you will have to fix some elements in the checkout like the display for the shipping/payment methods.
I performed a little test in your website and I couldn't reproduce your issue with the address (and I used Chrome)

By the way, do not send me private message, use the "contact us" form instead.
