Astral Ward Cloak, reward for the "Honorary Astral Ward" collection, is level 0 and missing upgrade slot

[Esterie.7409]

This is regarding the Astral Ward Cloak, the reward for finishing the Honorary Astral Ward collection. I finished this collection a few days ago and put it on one of my characters, only to be very confused why I couldn't slot an exquisite jewel into it like other exotic back items. Apparently this cloak is level 0 and thus cannot have anything beyond measly pebbles slotted into it. As this collection is kind of involved and the item has exotic stats, I believe this is a bug and hope it gets fixed.
