Fault codes

Welp I got these codes today from my understanding the first two are having to do with the o2 sensors and the last one is an air mixture to rich code idk how that's possible that I'm getting those codes since the sensors are off and I have also been running this tune for a long period of time. All though the other day I did have the sensors unplugged when I turned the car on so maybe that has something to do with it if anyone could shed some light that would be great I don't think there's anything to worry about.

Unplugging sensors when the DME is awake, even with the car off, has given me codes (i.e., plugging MAF or CP sensor to remove intake/CP), albeit shadow codes not an active CEL. Clear them and see if they come back

Nope they never did come back weird how they took so long to show up if this is the case.
