The unwanted interaction between Charm and "Ngamahu, Flame's Advance."

Since this league. Charms are considered as non-unique jewels.

There is a spot near the bottom left of the passive skill tree that grants a bonus from Ngamahu, Flame's Advance (Chieftain Passive) that is +3 per jewel. So some nodes near sword mastery,axe mastery and shield mastery(bottom left of skill tree) give us +6,+9 strength(3 charms).

If I unequip a charm.the bonus(at that spot) will go down from +9 to +6. so charm triggers Ngamahu's Flame's Advance.

This bug still exists.
And what OP didn't mention: Ngamahu's Flame also affects the nodes of the Primal Asdencency itself.
