New menu items align wrong

I’ve tried to replace some menu items, and when adding the new menu items they all align on the left side. The best example is the outdoor reclame categorie in the menu. You will see some items to the left, then a blank space and some old menu items on the right. Is there anyone who knows how I can get a normal menu where all the items are aligned right?
