Hi, 

I keep missing notes in that song. You can here the notes but there is no note displayed - only two vertical green lines. RS treat this as a missed note even though you cannot see a note to play. 

It looks like the charter put notes on the 5th string, which is not available on the bass path.  They need to either add the notes higher up on the 4th string, or remove the notes on the 5th string in eof, and remake the chart.
