In BIAB -- try loading the drums or the percussion part first, and it will be on the Drums track. Use highlight, copy and Paste, either in Notation or PianoRoll window to paste that part onto the Melody or Soloist track.

Then load the style that has the other part, drums or percussion, onto the drum track and let it generate by pushing Play.

Don't forget to rechannel the Mel or Sol to channel 10.
