Bug on rewards for achievements in minecraft bedrock

There are several items that cannot be unlocked even though the achievement requirements have been obtained.

The item remains locked even if the achievement is 100% completed

I'm sure this item was not removed because it is still available in the character creator menu.

Here are the items:
• Victor's Wide hat
• Victor's Overcoat
• Victor's Tunic
• Victor's Pants
• Victor's Boots

This problem was also experienced by my friends.
