KD variations?

Ok so I look at my stats here on way point and it shows I have a .842 kd but when I looks at my KD in game in the service record it shows -0.3. Yes I know it’s bad and it really doesn’t bother me. My question is why the difference in KD from he site to the in game service record?

Thanks

The 0.842 K/D is from your Arena stats only. You probably didn’t factor in your Warzone K/D.

Ok it is not showing up in my profile for some reason but my arena service record has a KDA of -0.2

The screen shot is not showing up I mean.
