Here is an example of one folder:
The by Author list is 78 pages. The first 38 pages are okay, on page 39, names are listed out of order (I'll just type first 3 characters for example)

Kyl
Kyl
Lan
Lad
Lad
...
Lam
Lam
...
Lam
Lan
Lan
...
So one occurrence of name beginning Lan sorts before names beginning Lad and the other occurrences sort correctly following Lam...
