I'm learning how to use Anki to study Japanese. In the anki manual it says:
"Thus, if you select your 'French' deck, the subdecks 'French::Vocab' and 'French::My Textbook::Lesson 1' will be shown as well. For new cards and reviews, Anki fetches cards from the decks in alphabetical order. So in the above example, you would get cards first from 'French', then 'My Textbook', and finally 'Vocab'."
How can you be shown my textbook cards after you have gone through french cards when the french deck is solely made of my textbook and vocab cards?
