Layout problem Please Help !

Hi i am using twnII template and K2.
Everything is fine except K2 categories view. I have two modules in the position right_bottom but they are inside the categories layout instead of the right column.

The problem is here -> http://hellasview.com/hellasnews/index.php/athlitismos

Please take a look cause I am searching 4 hours to find a solution but i cant find anything.

Thanks in advance

I've validated your site using w3c validator and here are results >> http://goo.gl/wWH1J . In article code you probably missed one <div> tag which destroy the layout.

yes i realisized it when i deleted my articles inside that category.
Now its all OK
Thanks man
