If the Filter function is set to [ON] in item lists such as Inventory, Duplicate Items, or Wishlist, items that do not match the selected conditions will not be displayed.
Please check whether Filter is set to [ON] in the bottom-right corner of each item list.

If you select [Save these settings] when configuring the filter and then complete the settings, the filter will remain applied even after you move to a different screen.

＜When owned items are not displayed on the Style or Cocorium Decor screens＞

Items that have been moved to Item Storage will not be displayed.
You can make these items appear again by tapping [Return to Inventory] in Item Storage.
For more details, please refer to the “Item Storage” section in the in-app Help.
