Kobo - Sort authors by name

[carlese]

Hi everyone,

after fiddling around I managed to have th author_sort in Calibre by name (I used the "copy" parameter in the tweaks so instead of "Brown, Dan" I have "Dan Brown"), but no matter what I do, when I transfer my ebooks (KEPUB format) to my Kobo they are always sorted by last name. I see them in the correct order in the author tab, but not in the main book tab. What can I do?

I also tried to convert author to author_sort in the metadata plugboard but still no luck..

Thanks for the help!
