Help!: Turn directions wrong

I printed out the notes for this ride - http://www.mapmyrid e.com/ride/ united-states/ ca/morgan- hill/76012551366 2150231

While riding it we noticed that the turn directions were sometimes wrong - left instead of right! An easy to see error is at mile 15 when it tells us to turn right on Canada instead of left.

 Any ideas on why this maybe. Not all turns were wrong, but many were.
