I just found out that Nashville Notation only records in major mode?
The chord progression [...] is Am-C-F-Dm-E
Here comes the question.
I am currently selecting Am mode in BIAB
Nashville Notation display：1m - 3b - 6b - 4m - 5
I don't understand why it's 3b instead of 3

So, all confusion aside, what's the answer to Expert Mix's original question about Nashville Notation, which was actually pretty clear?

The behavior of BIAB in using "3b" for C in A minor suggests that numbers by themselves represent degrees of the MAJOR scale, and that flatting notes is one of two ways to notate a song in a minor key, the other being to represent it in the relative major (Am = "6m" in C.)

Is this correct? Is this how Nashville Notation is supposed to work, or is this a quirk/bug in BIAB? I'm guessing it's normal but can't confirm by casual Googling, and now I want to know myself.
