This scene you've played is a size 3 scene not size 4. Setting the size on Debug Mode or replaying scenes with incorrect sizes can lead to errors like this as not every outfit will be available for each size. You can fix it by setting size to 3 and replaying this scene the way it was intended
As for the files itself, as the game is still work in progress so some of the outfits will have placeholders. They exist for implementation purposes so game will already know to call them in a script and show them in game when they will be completed
