In the first aircraft.cfg of your image (left side), it shows that the sim=cs757-300_RB535E4Bw, yet in the second aircraft.cfg (right side), it shows that the sim=cs757-200_RB535E4Bw.

What do the texture.cfg files show (found in the texture.xxx folder), and is there only a single folder for the livery, or more? I know in your first post, you stated you had duplicates, but are they still there, or did you delete the duplicates?
