It is becoming apparent that you do not know how to use the results  
from either system. The progress of science would be safer if you get  
some advice from a person that knows what they are doing.

Different parametrizations. If I had to guess I would bet that the  
gender coefficient is R is exactly twice that of the one from SPSS.  
They are probably both correct in the context of their respective  
codings.
