I'm digging in to this today. I'm going to see what happened and clarify what the gear should look like. Apologies for the confusion.
At this point it doesn't matter what it "should" look like. Many people bought the packs because of the look on the picture (the "fixed" set) and many other people bought the gear because of the item preview (the "broken" set).
As I see it, the only way to fix this issue is to have both appearances in the game and give people the possibility to exchange one for the other.
