I used to design record sleeves, so have a bit of an insight of what happens behind the scenes, so to speak.
Record exec's, band management and other management can't help themselves but get involved, so if the band or record exec's choose a track list, it's not unusual if someone comes along at the last minute to change things, everything from cover image, track order, even small print, nothing is off limit to last minute change, so this is where a lot of errors occur. If something is changed and someone in another part of the process isn't informed then you'll get these anomalies.
