If we set chord display normal, set A minor key, enter Am, Em, Dm, Em, then all seems correct.
Now change chord display to i-types, or Nashville.
The Am chord is displayed as a 6m or vi chord. It is but only in the key of C!
The Am chord should be a i minor or 1m chord in the key of A minor.
Chords in natural minor keys follow the pattern, minor diminished major minor minor major major.
i – A minor, A minor seventh (Amin, Amin7)
iidim – B diminished, B minor seventh flat five (Bdim, Bm7b5)
III – C major, C major seventh (Cmaj, Cmaj7)
iv – D minor, D minor seventh (Dmin, Dmin7)
v – E minor, E minor seventh (Emin, Emin7)
What am I not understanding? or is this a known bug?
