Woocommerce and product view

Hi,

in Woommerce my products are always displayed shifted.
See here:

After searching the web for hours, I think I am the only one with this problem ??
How can I setup the Shop to display the products in a evenly row?

I have no glue about PHP coding (a designer helped me setting up the shop and did coding for me). So a plugin or build in version would be great ??

Thanks and Regards
Thorsten
