Product categories bug, only showing first item

Issue visible at: http://www.tsemppari.fi/kauppa/tuotteet/kategoria/vaatetus/

I've manually translated the shop into Finnish, but I did my best to make sure not to mess up any coding.

I have no theme selected (doesn't seem to make a difference).

For some reason it seems like it clumps everything in the category into one post, as if there's a divide it's missing.
