how come my corrupted creeper cape is not in java/bedrock?????

I feel this should be obvious but if you have these capes in Dungeons II you should be able to redeem them in java/bedrock especially since the designs are so unique and good looking! would love to see them in the vanilla game, i felt kinda disappointed after buying the game and realizing it's not for the base game.

I hope this is due to change in time, other than that it's a great game and very fun!
