Thank you everyone for the suggestions so far.
TL;DR: tagging applications suggest that there's nothing wrong with my file, and I've rephrased the question at the end of this post (since I may be asking a different question than I think I am).
'Prefer online information' is not selected. I mentioned .nfo files because the site for the recommended addon to verify the tags mentioned .nfo files and being unable to update tags in audio files. There are no existing .nfo files related to the audiobook in question.
At this point, I am going to stop pursuing anything with Metadata Editor (it will probably work, but not well for my goals - I don't want to have to set the genre for each book manually), and I am not going to worry about .nfo files (they were mentioned only because the site for Metadata Editor makes several references).
I'm going to rephrase the question to see if I can address what I'm seeing as the issue/challenge/problem (and make sure I'm asking the question I think I'm asking):
I have an m4b with tags.
I think the tags are done correctly (two different tagging applications show them as correct).
Some elements of the tags are scraped properly (artist and title).
One element, genre, (possibly other elements that are not are not set in this file) is not scraping.
I will have a large number of audiobooks that I want to scrape into Kodi.
I do not want to have to set the genre for each book in Kodi (the tool I'm using to create the m4b - m4b-tool - files uses the directory structure to identify the genre).
mkvtool was not intuitive for me, so I'd like to avoid that; I might be willing to work with it if someone can do a truly step-by-step example (setting tags, assembling the files, &c.).
Having said all that, how do I get genre to scrape (is there a specific tag I should be putting the genre in - mp3tag suggests I have it in the right place)? This may be relevant to other tag frames as well (I have only run into it with the genre tag - there aren't a lot of others set in this file). Or, more generally: for m4b files with MP4 format tags, what frames should be set for what information in Kodi (I care about: artist, title, chapters, genre; I'd like: year, author)?

But since you mention NFO files, it is possible that you have "Prefer online information" setting enabled, in which case any genre value held in the album.NFO will override that derived from the tags.
An example fule would be the best way for us to check what is happening, or at least if atgging is the issue.

Maybe @DaveBlake will know.
