Death Recaps not recapping correctly CLIENT

When I die, the death recap will tell me who killed me, but will vastly underreport the amount of damage that is being done. It happens every single time I die. When you add up the numbers and the percentage of damage done, it will add up to like 30%, and something like 800 dmg total, despite being a full build Renekton with 3500hp. I can recreate it by dying. Every single time I die, doesn't matter if its TT, ARAM, SR, doesn't matter what character I am
