I'm having a problem getting comments to show up in my book details in my Nook library (oldest e-ink version) and in my Calibre Companion app.
Because it's happening in the Nook and not just the CC app, I'm pretty sure it's something Calibre is doing when it's sending the metadata.
The thing is, I have no idea why this started happening.
I did three things right before it started happening.
1. I edited a few books to get rid of junk in them. Coulda messed one up, for sure, but I did run the check on each of them before saving and closing.
2. I changed how Calibre shows dates through Preferences and Tweaks. It worked after the fact, and I'm confident I did it correctly.
3. I set up a news download and Calibre automatically sent it to my connected device, but then I deleted the news books and the custom recipe too (it was really just a test and I decided against using Calibre for news).
With the very next connection a few minutes later, I realized my comments weren't showing up in the books I sent to my devices. At that point, I undid all the things I'd done in Calibre, but none of that fixed it.
I deleted ALL my books in Calibre Companion, then resent just a few, and that didn't fix it.
I cleared the cache and the data in the Calibre Companion app in Android settings, basically everything, and set up CC again from scratch.
I cleaned the database. Didn't fix it.
I found out I could uncheck "formatting in comments" and the comments DO show up. I figured I could live with that.
But then I realized it was happening in my e-ink Nook too. I know it's old, but it works and I use it as my primary e-ink reader.

Since I can't change any settings to make the comments show up here, I realized I was going to have to figure this out.
I reinstalled Calibre.
I wiped all my Calibre user data and configurations and reinstalled Calibre again.
Basically, other than wiping Calibre and Calibre Companion and starting from scratch and rebuilding my library from the books themselves, I don't know what else to do to fix this. But I depend on the comments (book descriptions) in my library of 2321 books and I need it to work.
What am I overlooking?
I really want to fix this.
