BIAB struggles with Cb, Fb, B#, and E#. I think you can right click on the note in editable notation and force the accidental. BIAB views the note based on the note number (which could be either a Cb or a B - same note number, same pitch). So, if you select Force Accidental and select Flat, it should display it as Cb.

The user manual says this:

Quote:
Force Accidental - If a note is being displayed as a sharp, but you want it to appear as a flat (or vice versa), you can force that here. Notes like Fb, Cb, E#, B# can be entered. To do this, right-click on a note (like F), and set the forced accidental to #, and the note will appear as E#.
