Crit dmg chance bug

[Coolin2002]

I have 206.2% critical chance and I'm using Livid Dagger but I'm only getting critical damage about 75% of the time and it should be every time, why is that?
I used to have AOTD and get crit dmg every single time with 112% crit chance.
Is any one having this problem crit dmg problems?
