You can get up to two dragon eggs in Bedrock, so its not a bug unless you get a dragon egg the third time also
still an issue in 19.81 hotfix
add "Enchantment Table" and "Enchanting Table" to the list too
Breaking pumpkins from my farm, (maybe exit the world), try trading pumkin.
You're talking about "enchanting" as an adjective but its also a verb similar to crafting (as in crafting table) or smithing (as in smithing table).
Its also an issue of consistency and pattern, isn't it?
