Here is my first screen shot. It's a sample of mobi files created by Calibre from 2014 through 2018. (Specifically, I'd imported Word docs and epubs, edited their metadata, and converted them into these mobi files).

The file names were auto-generated by Calibre. As you'll see, Calibre added both authors' names to the file. (You may noticed that they are Last-Name-Comma-First. There's a reason for that, but I don't want to get side-tracked on that issue right now.)

However, any ebook I create now has only the first author's name.

PLEASE NOTE: I'm providing this screen shot only to prove that I am not crazy (many people suggested I was wrong when I said Calibre would add both authors' names to the file). Ultimately, I don't care about file names. All I care about is the metadata. I mentioned the change in file naming convention merely only because I thought it may be related to missing metadata I'm experiencing. It's possible they have nothing to do with each other.

With that in mind, my next post will be the important one because it will provide screen shots of the missing metadata. So if people want to ignore this post, that's fine by me.
