Hello again

When I save a realtrack as a "performance track" to my song, then play it back, the audio is distorted.
This is what I've done:
1. Created bass, drums and guitar as performance tracks (wav or wma)
2. The track is highlighted in orange with a star
3. I then disabled realdrums & realtracks in settings
4. Played back the song and the audio distorts, as if each track is doubled e.g. 2 bass tracks playing

help!
