Cts-v codes

I've had my caddy since 2016 when I did a lot of work to it. (742HP 702 TQ) It's not been driven much since i got my first TrackHawk 2018. I'm preparing to sell it BUT i've got the attached codes I can't get rid of, i've put new O2's yet the pump and O2 codes remain. I've uncheck everything I can find yet their still here. The car runs great.
Looking forward to some help:)
Thanks Attachment 151276

Permanent codes can’t be gotten rid of by clearing them. The ECM must see corrected conditions before they will go away. If the they are set prior to turning them off, I think it’s too late. I’m not sure what the fix is, if there is one. Maybe a full SPS rewrite.
