Steps to reproduce the bug

I do not know whether the name is correct, but by 'quick selection bar' I mean the list of letters A-Z on the right side of the contacts panel

1 Unselect 'start name with surname' from preferences, if selected
2 Go to the contacts panel
3 Change the sort order to 'surname'
4 The quick selection bar gets messy

In addition, when selecting a letter from that bar you do not go to the first surname starting with that letter in the contact list but to the first name starting with that letter

Expected behavior

The quick selection bar should always go from A to Z in alphabetical order and should allow the user to jump to the first item starting with that letter according with the selected order mode

Actual behavior

The quick selection bar seems to report the letters in the order they first appear in the contact list.

For instance, my contacts are shown in the 'Name Surname' format. So, when they are sorted by surname, they look like

FirstName America
SecondName Brazil
ThirdName China
FourthName France
LastName Italy
...

and the quick selection bar looks like

F
S
T
L
...

So, if I want to jump to surname 'France' I have to find where the 'F' has been placed in that crazy order. Most importantly, if I push 'F' I am shown 'FirstName America' because it is the first item starting with 'F' although I would expect to go to 'FourthName France', as mny sort mode is by surname and that is the first item with a surname starting with 'F'.
