having trouble with blood of the karui

well the issue seems to affect when you use a necro build with zealot oath and baron, the potion dont give you any health and bugs the rest of the health potion you have equiped, consumes the charge but dont work, seems to be a common issue cause i found out in another page that people are complaining about it https://tldrexile.com/pathofexile.com/forum/view-thread/2739062
I had the bad luck to find out this bug on a tier 16 map and lose exp when i died, so plz fix this.
