The title is self-explanatory, as you can see in the screenshots, the Italian translations for the "Chunk Builder" option button are weird, and overlap other buttons, making them illegible.
Suggestions:
Chunk Builder: Threaded -> Aggiorn. Chunk: In Thread
Chunk Builder: Semi Blocking -> Aggiorn. Chunk: Parziale
Chunk Builder: Fully Blocking -> Aggiorn. Chunk: Totale
The translation is not done by mojang (it's done by the community on crowdin.com)
