Plex ignores the ID3 tags of my audiobooks and plays the titles in the wrong order

Server Version 1.18.7.2457

I have some audio books and would like to have them managed and listened to by Plex - just like I organise and watch TV series via Plex.

My audio books are all tagged properly.
Track # - Title Name - Author - Book Title - Cover - date etc…

All the books of an author are in the same folder.
The file names are structured as follows:

Track# - Booktitle . mpe (e.g. “01 - the holy bible.mp3”)

Although I have enabled “Prefer local metadata | When scanning this library, prefer embedded tags and local files if present” in the settings, the 4 albums from the same author in the same folder of Plex are always played as ONE audio book:
01- Audio book1
01- Audio book2
01- Audio book3
01- Audio book4
02- Audio book1
02- Audio book2

In this order, of course, it makes no sense at all, especially since the titles are played in exactly this order.

What am I doing wrong?

Of course I could manually create a separate folder for each book, but I would like Plex to use the tags embedded in the mp3 files to structure them.

Of course I could manually create a separate folder for each book,

You have to do this.
You can use software to do it for you, e.g. mp3tag

WOW, that was quick! Thanks!!

mp3tag is great, I use it since years… to set my tags right and to import my mp3 to iTunes. I let iTunes organize my complete library and iTunes puts all mp3-titles of different authors into the same folder (author name)
If I reorganize the folder structure, iTunes probably won’t be able to handle it.
I gave plex access to the iTunes Audiobook folder …

Plex has no support for Audiobooks. So your audio files must be organized exactly like music:
Music > Album Artist > Album Title > Tracks
or analogous for Audiobooks:
Books > Author > Book Title > Chapters
