Did not get the Mcc cape or the crown when i did all the tasks.

When i did the last puzzle of the Mcc mystery cave task I did not get the cosmetics. I have gotten all of the other cosmetics from the other challenges but not the cape or the crown. And when i completed the task it did not show the pop up screen that i got it but it has shown on the other tasks when finishing them. So is there any way i could get them?
