Magic Boy (2007) Cast-Mistake need update

[heinz Germany]

Under Pos. 38 (twice is twice) there are twice the same ??? 1) Ho Ga-Wa 2) Leo Ho Ka-Wah - Are those the same person, which must be merged?
See this capture: http://hkmdb.com/db/movies/image_detail ... ay_set=eng (Can be removed after fixing)
I don't believe 2 ??? play the same role...
