unable to add new categories to enum

so i created an enumeration and declared a variable with the enum. I have been using it for a while and needed to add a new category to my enum. I added the new category, but i unity keeps telling me that a definition does not exist for the new category of the enum. A dropdown list populates and shows all of my old enum categories, but the new one simply will not show up. I have no compiler errors(except the no definition). I am rather new to enums, but i dont understand how i can access some of the categories but not all of them.

public enum CharacterState { Idle = 0, Walking = 1, Trotting = 2, Running = 3, Jumping = 4, Slicing = 5, Aiming = 6, Recoil = 7, Recoil2 = 8, }

(I'm unable to access Recoil or Recoil2)
