Installed INPA this morning, love it found a few things that im not 100% on, wondered if you could educate me

1st one, had this Lambda bank 1 and bank 2 red, is this normal, i have an N42 engine (2.0)

This may explain the lambda issue, not sure?

I had one engine error code, Camshaft sensor inlet, any ideas, 2 screen shots below, car its self is running fine, says at bottom error will not produce light on dash

I had a little look at the steering wheel angle stuff and it said this: any ideas?

Could the fault codes be old? How long do they stay in system if not cleared?
