Sorting by "class specific" is seriously misleading. In our bank, using this view, you see a section on top that isn't named then a Druid section, followed by Priest, followed by a very long section that has no header (and thus appears to be Priest only), followed by Paladin/Rogue/Shaman/Druid, followed by another very long section with no header, followed by yet another Druid section...etc. I'm hoping there's a way to get this sorted a bit more logically.
That looks like a bug to me. That's definitely not supposed to be looking like that.
