I’ve just done some testing here, and I was able to reproduce your error. I was also able to get around it by temporarily removing the 0.1 uF capacitor when initially writing the ArduinoISP sketch. Would you please give that a try?
Also: we looked into the “misleading” LED instructions. It turns out that the last batch of these LEDs that we received from the manufacturer (1) had the plastic lenses backwards, so that the flatted side was on the wrong side, and (2) we did not notice at receiving time. (Yikes!) Thank you for bringing that to our attention. As usual, the only way to be sure is by the lead length. :(
