There was a time player stats were accidentally included with an update before it was very quickly patched out.
Issue is, the same bug from before (Kill total, missing AT stats) is still present.
They accidentally released an unfinished product and recalled it because it was unfinished, then released the same unfinished product 2 months later and called it a feature.
I wonder if the totals are for total squad kills from your AI but the kills you did are your weapon totals from when you are in control.
If that’s the case I have Terminator level bots lol
