Wrong database about my kd and hours

Since r6tracker renewed,I find that my database on r6tracker is wrong.Last season i saw that i have played 2547hours general win65%,1.68kd in general,now i only saw 1.38kd on tracker and 1000hours

Hi, the way we calculate Lifetime stats has not changed, except from the Playtime stat.

We’re now using the same value the Ubisoft Connect launcher provides. This is the only playtime stat Ubisoft provides now.

But why i saw the correct data on your app tracker network that on phone,website and the pc app both are incorrect data.You mean that ubisoft calculate wrong?
