White Dye is called Bone Meal in the inventory instead of being called White Dye.
The dye still works like normal white dye but it just has a different name.
The way I found this out (and how you can replicate this) is by crafting white dye from bone meal or a lily of the valley.
This bug might be in previous versions, but I only noticed it in the current Minecraft Bedrock version (1.18.32).
Thank you for your report!
