Yeah, listen to a jazz teacher;-))
There is a reason why I told you to use the m6 chords.

See, of course, we jazzers like to play m11 chords and m9 chord, and usually they sound better. The 6th is the avoid note in dorian, but it`s also the most important note (along with the third of course) in that scale, because it defines it.

So piano and guitar players would play a mixture of these chords (and btw plenty of quartal chords too in the modern playing), but and here`s the clou:
They know that they are in dorian mode. BIAB does NOT. So, a jazz bass player can throw in a major 6th once in a while and will make it sound dorian. But BIAB will not know if it`s dorian or aeolian or even phrygian if you type in a m11 chord. Coz all of these scales have a m11 chord in them! If you`re lucky it plays a dorian phrase, since it`s the most used minor scale in jazz. But how can BIAB know? Maybe if you type Dm9, or 11 and set the root scale box to "C". But the safest way to go is to type Dm6 and the whole BIAB Band will play Dorian for you.
