Gen 4 e38 5.3 only have bank one fuel trims

I did a swap in my Colorado the motor has a mild cam in it and I?m trying to sort out my idle to start. When I have my scanner open I can only see bank one short and long term fuel trims. Bank two is blank for both. I do have activity (switching) as normal on both bank one and bank two o2 sensors. Does anyone have some advice as to what could cause this?

It would be a whole lot easier to help if you could post the tune and a log file.
