I just noticed that trying to sort a deck by edition, when in ungrouped card view, simply doesn't sort in the correct order

An example is here https://deckbox.org/sets/2421923?o=d&s=e&v=l

You can see Arrest (Mirrodin) at the top
And Blinding Beam (Mirrodin) and Bonesplitter (Mirrodin)

Somewhere in the middle of the list. Not sure why that is, but it's certainly odd.
