I seem to recall in an older version of BIAB that when selecting Roman Numeral or Nashville Notation in Chord Display preferences I could also make a tonic minor chord appear as a "Im" in a minor key instead of a "VIm," but when I deselect "for Roman numerals in minor keys, use relative major" in Preferences 2 it still displays the tonic minor as VIm instead of Im. In Nashville notation it displays as 6m instead of 1m.

Is this a bug or am I just misunderstanding this option? I've tried this in versions 11.5, 12.5, and 13 and none of them display properly. If I choose to view in Roman numeral or Nashville display I would prefer to view the tonic minor chord as a Im and not a relative minor.
