Warzone Plunder stats wrong

My placement result in Plunder is constantly wrong, particularly if I win.
If I place 1st as a solo against teams of Duos or Trios it often says I placed 3rd or 4th, as it seems to be ranking me based on some other metric such as XP or some other score. So teams with more people are placing higher despite me winning the game.
The win is based on Cash, which is a metric that doesn’t appear anyway here.

Probably 50% of my wins in Plunder come up as 2nd, 3rd or 4th on this app/site incorrectly. It needs to follow the actual game result, which shows a win based on Cash.
