It is necessary to think of the 1/2 note interval (G# and G natural) as one that will create dissonance. A flatted second is also a flatted ninth. This flatted ninth is a standard interval used in jazz chords. I also think that the spread of octaves where the two Gs exist make it a less noticeable effect of major and minor together. Maybe it is about an arpeggio. If I remember correctly, you are expected to move quickly past the flatted 3rd so that it almost gets delivered as a "pickup" note. Check your note values and also someone else. It has been quite awhile since I learned of this relationship in intervals.
