What browser are you using, Dave? Part of it could be a browser issue, but I don't think so.
Curiously, I just checked the store in Internet Explorer 11, and got a slight variant of the problem you saw. Oddly, the Norway video was just below the Ctein one, reversed from the way you show them. I could read all of the Norway description with no problem, but there was still stuff unreadable at the bottom of the Ctein description. It looks to me as if each "block" showing one item is the same size, and they tried to put just a little too much text into Ctein's block.
