My Founder's Cape is gone, kinda.

This is an issue that has been bugging me for a while now but never got resolved so I had to report it. I bought Minecraft Bedrock on windows 10 before the better together update and while it was still in beta. As a reward I got the Founder's cape, which is awesome! However I recently realized that even though I bought the game while it was in beta and I got the cape, the cape has vanished from my dressing room/character creator. I have 1 skin that has the cape and I mustn't change it otherwise I'll most likely be unable to equip it ever again. Only cape that I have is the pancake one but not the Founder's cape. I wish this could get fixed so I could use it on more skins rather then just the one I had it equipped on years ago.
