Favorites feature misspelled

I have noticed when activating the "Favorites" feature from the user & groups panel, that the word "Favorites" is misspelled, it is spelled "Favourites"

American English and British English have many differences and are considered as standard dialects. The English I learned is the American English since I live in North America.
