Update, upon reading the log files, I believe I know what causes the incorrect icons to appear for songs on the wrong page.
Link to thread; Jam Emote Wheel is bugged.
It constantly calls the downloaded icons expired and out of date on startup, or it attempts to unload them if the Jam Wheel is flipping through pages too quickly, because of the memory limit.
As for the issues with Ghost Jam Tracks or the final page not working correctly is beyond me.
