Behaviour display content

Hi Staff,
I've published 8 article, with same image size on layout fullwidth;
now happens:

In the first four articles shown everything OK, but for the second block of four articles, only three are aligned the last of the four is a line lower, as you can see here (if you play the next block): www.veronalive.it/index.php

Where am I wrong?

many thanks
