Cull the Weak not activating / armor enchantments not staying enabled

[Mr.Red]

illithid power "Cull The Weak" is supped to activate and kill any target when their health is below the amount of Illithid powers you have. I currently have 6 powers on my character so therefore any enemy brought below 6 hp by my character should die. After reaching The Duergar base, Cull The Weak will no longer activate. It is enabled under my passives but never activates no matter if I use spells/Melee/ranged attacks. I tried reloading an old save to see if maybe there was a corruption in the file but no same thing happened as soon as I reached the Duergar.

Also I have enchantments on my armor relating around the lightning charge mechanic. When taking a long rest or teleporting between waypoints the enchantments will no longer be active unless I strip my character completely then re-equip my loadout. Seems to only happen to my main character and not any of my companions.
