I've just looked on my PC and in the folder (artist, Mikhaïl Pletnev) is just the correct image. No sign of the other.
HOWEVER, I’ve now looked again on the UI on my iPad and the correct cover is still at the bottom right but a different wrong image has replaced the first one, top left.
The recoding is Argerich and Pletnev playing his transcriptions of Prokofiev's Cinderella. The first wrong image was of a youthful Argerich and today’s is a Pletnev album cover.. I this morning loaded on the B2 itself a disc of his playing Beethoven and this disc illustrates the same recording but is not the cover on my CD and I didn’t load cover art anyway!
Don’t trouble much about this. It’s such a minor thing and the music's the point.😀
