For some reason adding the cards from the deck lists results in having them assigned as "Unknown Edition" even though I have the default edition set to Commander Anthology. I've even tried making a CSV file that explicitly defines the cards as being from that edition and they still won't import correctly.
I've gone ahead and included the CSV file I used to try and import the cards to my inventory. I'd like to be able to add all 4 decks into my collection in one go, rather than having to go through all 400 cards one at a time.
I had the same issue. Luckily I added only one of the decks and I figure I'll wait till the issue is fixed before I add the others.
If it helps I added them via mobile chrome 58.0.3029.83
