When you use the command /structure load {StructureName} ~ ~ ~, Instead of returning 'structure loaded successfully', commands.load.sucess appears in the chat box.

What I expected:

Running this command would return 'structure loaded successfully' or similar.

What actually happened
Running the command returns the untranslated string 'commands.load.sucess'

Structure generation works fine.

Reproduction Steps:

1. Make or load a world in 1.17.10 of Minecraft PE.
2. make a structure using a structure block.
3. Run the command /structure load {StructureName} ~~~

Minecraft will print commands.load.sucess.
