The Hexblade attack and damage

[sandor7]

I'm running a hexblade warlock. The Hex Warrior feature says "when attacking with a melee weapon that you are proficient with and that lacks the twohanded property, you can use your Charisma modifier, instead of Strength or Dexterity, for the attack and damage rolls." This is not reflected on the attack and damage modifiers. Why is the charisma modifier not reflected in the attack and damage, and how do i fix it?
