the vote div moves in some type of nodes.

Hello we have a web with a few cck node types and all run great but in one of the node types the "vote" div isn't display well.

Here is the well page:
http://recbib.com/oposiciones
And here is the strange page:
http://recbib.com/formacion

I don't understand why in "formacion" node type it's display wrong.

Thanks

Oskar
