Stats takes the Display option instead of Tooltips

Right now it takes whatever text is defined in Display: '' of a certain stat and we have no control over whatever is in front of it (i.e. the +, x and %). The Tooltip section doesnt have a purpose it seems.

CRITICAL_STRIKE_DAMAGE:
  Enabled: true
  Display: '&7Critical Damage blablabla'
  Tooltips:
    Additive: '&a +<value> &7Crit Damage a'
    Multiply: '&a +<value> &7Crit Damage b'
    Compound: 'x<value> Crit Damage c'
  BaseValue: 1

No matter what type of crit damage you put on the item, it will always show ...blablabla and in none of the cases ...a b or c.
