The Road of Exile 2 - Chapter 1: Survival Ritual - Error in Candlelight Reward

The system shows that this reward is 8% maximum health, but I actually received 5% maximum health. I'm using Chinese and posting the translation. The game reward image has been saved and shows that I received 5% maximum health. I don't know how to send this screenshot in the forum. A difference of 3% in maximum health is of great significance to me. Is this a bug? Can it be fixed?
