Voidheart Iron Ring - not applying chance to bleed or chance to poison

"

Hi
For resume : when i eqquip my voidheart, the chance to poison and to bleed are not effective.

I should be to 100% for each whith that item but i stack to 80% bleed and 60% poison.

I was asking myself if it was only the character sheet who was bugged so i make some tests ...

I'm not poisonning ennemies every hit and some monsters don't explose when i kill them (it should be cause i'm wearing Haemophilia who make monstes explose when they died while bleeding.)

Sorry for my english level ;)

Hello. I've noticed that on my offence skill tab i see only 10% chance to poison, even though i have 37% from voidheart and 10% from tree. where is the issue? does " chance to poison on hit " and " chance to poison with melee hit " not stack?
