I think this is old hat for Rick and the others gurus, but anyway...
Why the first flat is so distant from the notes?
Of course the solution is layering, but I'm surprised. It seem that the flat is 3 steps behind, not just 2 as expected.
See: Bug: Accidental spacing on split stem chord (https://forum.noteworthycomposer.com/?topic=6977.0)
This is a rare formation. Most unison chords just have the two unison pitches.
For the piano, these 2 measures are essentially the same:
Otherwise layering is the answer. NWC seems to be evolving to where it is expected that 2 voices require 2 staves. This doesn't bother me too much as I use at least 2 staves. I just wish that NWC would get rid of the silly systemic barline when there is only one apparent staff.
...almost.

Yes, I know, fractionary "extra note space"...
