Overkill trophy bugged on bedrock [ps4]

So I'm 2 trophys away from my beautiful platinum when I ran into a quite disgusting issue with the overkill trophy [deal 9 hearts of damage] on ps4, simply put it does not work! I've tried everything and it doesnt register ive probably even dealt 20 hearts but here is a personal video example provided by me   https://youtu.be/t-Hg6R3KxiU
