Bonjour ! In the example from the lesson- dont Les Griffes de la Nuit. The English states- on Elm Street but it is not transcribed in French ?

Bonjour Shrey !

Here it's because "A Nightmare on Elm Street" is a 1984 American horror film, and as you probably know, most movie and book titles are translated in French, and not often literally :)

This film's French title is "Les Griffes de la Nuit" (i.e. The Claws of the Night) :)

Bonne journée !
