I don't know exactly the styles you are refering to, but I have already get this issue in other conditions.
Sometimes, I wanted a Cmaj9 and I got a C6 chord. Or as final chord I wanted a C69 and I hot just a C6 no way to get a C69.
As far I have understood, not all the chords among the +120 chord types are present in all the RealTracks, it depends mainly of the style and probably on some choices done during the recording of the RealTracks...I depends also of the instrument RT : you could get a hold Cmaj9 with a piano RT but not with a guitar RT or with a String Quartet RT.

It would be a good idea to get from PG Music with each RT a documentation listing all the possible chords for a given RealTracks, regular chords, shots and holds.
