Enchanting table captions translation key uses old pre-1.13 block ID from Java Edition. Despite sound event is correct (block.enchanting_table.use), the captions translation key is imported from Java without any implementation to Bedrock version.
Steps to Reproduce:
Open .lang files and check captions translation key of enchanting an item sound event.
Open Minecraft and check the item id by typing
/give @s enchanting_table
It seems fixed in Preview 26.30.27 and waiting for full release
