P1032 O2 sensors upstream TWC mixed up G3/3,G3/4

Does anyone know what this means.
I have replaced both upstream with bosch o2 that are correct and checked all plugs are connected. but this fault comes up. Not much online about it.

Hi I can bring up the order detail images then load the images of the boxes tonight.
I have also added the diagnostic screenshot. Both o2 are acting strange.

I cross referenced the old o2 sensors and the codes all matched.

Anyone had much of a chance to look at this. Handed the car to merc and they are clueless.
mercedes components 'g3/3 (left oxygen sensor upstream of the three way catalyst (twc/kat))' and 'g3/4 (right oxygen sensor upstream of the three way catalyst (twc/kat))' is mixed up.
