[Tarkir: Dragonstorm] Showcase Borderless Clan Card frames are missing

[khryus]

As per the title, Showcase Borderless Clan Card Frames appear to be missing. There seem to be at least one version per clan (totaling 5). I have attached the ones used for the legendary dragons, but you can spot them on different cards in the set.
