V8 Scanning WBO2 Not Working?

[nm2769]

I know it has to be something simple but I just cant seem to figure out what the issue is. I am well versed with V7.5 scanning and the WBO2 data is working in 7.5. I have just started using V8 scanning but for some reason I am not getting any data in V8. I checked the Cal PID in the V8 function editor but it comes up with an error that AD1 is not selected but you can see the AD1 voltage reading on the chart in the screen shot. Any suggestions?

Thanks
