A dumb question...you definitely put the Real Drums on the drum instrument and the Real Bass on the bass instrument? You can put any RT you want on any instrument track so if you had a RT bass on the bass track you can also have another bass RT on the guitar track if you wanted. If the original bass was midi and then you put a RT bass on the guitar part you would have both a midi bass and a RT bass.
If you didn't do this then I have no clue.
