Rockbox

I have version 3.5. I tried modifying my wps to add a playlist viewer and now when rockbox starts up it shows the right track at first and then it goes to one about 2 or 3 further ahead in the playlist when it seeks to the position it should be on that track. Only it goes to the wrong position of the wrong track. I'm attaching the wps I was using. It also crashes sometimes when I try to go back a track and then next to get to the right track. Also, most of my stuff doesn't have album art. One of the tracks it was on when I turned it off did have album art and it didn't make any difference either way.
