Hi Lizzz,
Welcome to the forums.
I suspect that you might have loaded the chords for a style's demo and that that demo has an organ melody associated with it.
If the above is the case, try muting the Melody (or Soloist) track and see if that helps. The "Mute" option is found as an M on the mixer. (See the top graphic below.) The "S" beside "M" is for soloing the track.
Just checking... have you loaded a midi file from the internet by any chance?
In the meantime, what is the name of the style you are using. (See the lower image below. If your BIAB view is different from mine, CTRL+T will switch between views.)
Regards,
Noel
