I have a problem when i generate a catalgue (last version calibre) with authors list with letter A /Æ and D/ Ð

No problem during the generation but when i open the epub with the viewer i can see double entry (with same link) for theses letters in the TOC ...

A precision : i use in parameter for hierachy presentation
Divided by fist letter
Combine letter with number < 0
Minimise if more than 200 elements (enough for 26 letters and other none ascii letter )

Auteurs
Auteurs comment par Symboles
Auteurs comment par 'A'
Auteurs comment par 'Æ'
Auteurs comment par 'A'
Auteurs comment par 'B'
Auteurs comment par 'C'
Auteurs comment par 'D'
Auteurs comment par 'Ð'
Auteurs comment par 'D'
Auteurs comment par 'E'
...

Have you and idea ?

Just an another request :
The list propose authors and all theirs books but without indentation
Do you think it's possible to add an option or to indicate where to change something if it's possible
Example

Authors 1
...Book 1
...Book 2
...Book 3
Authors 2
...Book 4
...Book 5

And not this presentation less visible

Authors 1
Book 1
Book 2
Book 3
Authors 2
Book 4
Book 5

Thank's for your help
