I have always used Calibre to load my Kobo Touch & its replacement Kobo Aura [epubs] but no matter what I try, I cannot get my authors surnames listed alphabet. I use the Kobo alphabetically on the Aura. I use Epub Kobo Touch plugboard - {series}{series_index:0>2s| - | - }{title}/ which includes series correctly on a reload, fine but the author are still all over the place. Both Calibre & the Aura are up to date & I sort the metadata on each author surname, christian name both in author column and author sort. On the aura, I might get two books by the same author listed and then a few others and the remaining two books by the first author. They are never in correct alphabetical sequence. In the plugboard I have tried author and author sort, neither works they are always mixed up. Help please, do not know where I am going wrong and what I can alter next - thanks
