Highest note won't play sometimes?

The highest note on my 30 note M4Music music box sometimes won't play, which is the A note (labeled as E on the sheet). I'm not sure what I'm doing wrong or if it's just the music box's fault itself, this never happens to any other note, and this isn't the case where I placed two eighth notes of the same note together, because all of my A notes are played as quarter notes. Not sure what to do about this, did I hole punch it too high or low or something?
