@advplyr commented on GitHub (Oct 9, 2022):

I'm not sure why the chapter title would be blank but when testing this I found other issues with multi-track audiobooks. Can you try testing again with v2.2.1?
And noting if you are using m4b/mp3 and single track or multi track.

Still happening.

Chapter titles get deleted and that chapters timing gets reset to the original value.

Sometimes chapters that get their title deleted assume the timing of the next chapter +1 second.

I think this happens when using Shift Times with negative numbers. Edited One book in three different ways, manually syncing the chapters, adding 1 second with shift time to every chapter and finally subtracting 1 second to every chapter with shift time, and this only happened when subtracting seconds. Will test further after my laptop has charged.

After dumping the chapter info with tone, I concluded that the chapters are correct, the issue lies with metadata.abs not grabbing the chapters correctly.

Been embedding metadata and I can’t reproduce this anymore. I noticed that Apple Books can only see the chapters metadata after I run tone -tag —meta-chapters-file manually, but that is probably another issue. If you can’t reproduce this we can probably assume some bad m4b file was causing this. I redownloaded the books that were misbehaving and everything went according to plan.

I wasn't able to reproduce it, hopefully just a bad file like you said. Thanks for following up.
