Thanks for letting us know about this.
It seems that the problem is a question of image clarity rather than instructor error. I've looked over the tab, and I agree that some of the fives look an awful lot like sixes. You'll notice in the regular notation that the correct notes are in place. Most notation programs are synched so that as you write in tab, the notation auto-fills...or vice versa.
We will look into this to see if we can improve the resolution of these transcriptions.
