Maybe try right-click - Track - Make all BB tracks regular tracks .. at least they become available again for whatever you want. However, all tracks will now behave differntly; they will only generate the highlighted section of any selected track(s). They no longer behave like BiaB and generate all .. you have to tell it to do that now (intentionally).
They start behaving like regular RB SEQ file tracks.

You have to Save As a seq file for this to stick, though (I think).

If you want to go the extra step you can then select all 8 of these tracks, then again right click - Tracks - remove tracks.
This deletes those tracks and moves the remaining tracks up .. freeing up the MIDI tracks you don't want, and making them available again as the last 8 blank tracks in the 48 available.

Image 1 - import BB file
Image 2 - Make Tracks regular tracks
Image 3 Remove Tracks option
Image 4 - all done
Hope that helps
