l5p duramax reading from 'DPF' table Not seeing all values?

New to this, but I figured out how to display The extra lines. I'm debugging DPF issues that I'd like to see DPF readings. I get DPF pressure variance sensor (volts) , but it does not show "DPF delta pressure*", "DPF inlet pressure*", "DPF Outlet Pressure*" (all ending in 'b1 (sae)'). I Am not sure if I should see it all the time, or if its something that it has to run for a few miles first. This may be a GM thing I suspect. This isnt a tuned truck, I bought the E41 unlock tool, but haven't tried to unlock it yet. Wanted to be sure I had the DPF sorted out first.
