Battleborn Stats Bug

I have been playing on pc since the game came out and I used to main Orendi. When the winter update came out all my stats with her changed. I had three quad kills and now I have none. It says I have only pushed 60 enemies away with nullify even though I pick it every time and have played countless amounts of games with her. It says I only have 2 meltdown wins when I remember winning at least 10. And when I checked Mellka, it said I have only hit 6 enemies with claw lunge but I have her rank 14 and her lore says 8/100 varelsi killed with claw lunge.
