I noticed strange authors smart list behavior in case of ebooks having multiple authors.

Lets we have three books:
Book1 - authors: Author1
Book2 - authors: Author1 & Author2
Book3 - authors: Author2

So in Authors smart list I can see:
Author1 (1 book)
Author1, Author2 (1 book)
Author2 (1 book)

To my mind expected behavior here should be (like in calibre):
Author1 (2 books): Book1, Book2
Author2 (2 books): Book2, Book3

What do you think is this bug or feature?

I use "Marvin - eBook reader for epub" v2.7
