Heiken Ashi doesn't match data?

 
I put the Heiken Ashi indicator on a chart, leaving the original candlestick there and not changing their colors.  The HA candlesticks were pretty different from the orginal candlesticks.  The highs and lows were close, but the opens and closes were off.  Anybody know why this is?
 

Look up how Heiken-Ashi candles are calculated, and you will find your answer.
