Brand new Aeroccino 4 whisk looks weird

I’ve gotten a new Aeroccino 4 today from the Nespresso website and when I’ve unboxed it I’ve noticed that the whisk has a weird indentation / scratch mark only on one side. Is this normal or I’ve maybe gotten a faulty one? I am a bit paranoid now about plastic in my milk or something. Any help is greatly appreciated, thank you in advance!
