why are tabs so complicated?

Why is tabbing so messed up in Storm?

I have:

class ..... {

  public ...{

  }

and then try to paste in:

  protected {

  }

but it keeps indenting it to be under public (i.e. 4 spaces instead of 2 from the left

if i select entire protected function and shift-tab, it removes all indent, if i then tab, it shifts 4 spaces again. impossible to shift 2 spaces and put it where it should be - smart tabs is disabled as it seems to make things even less predictable.
