Dead Eye Ability Triple explosion Bugged

So The dead eye ability Triple Explosion is not doing the 200% crit damage it should. I have the quad explosion skill selected and at 40% of enemy health it is a 100% crit chance, but when it crits it only increases the damage by 4k . its base damage is 14k and if its 200% it should be crits with 50k with the addition of 25% from the top skill. but its only doing 18k crits. please fix this as this is one of my main skills.
