What is missing? Switch statement seems correct to me but something is still missing

What is missing? Switch statement seems correct to me but something is still missing

The error information says the case for "Right" is not correct ??

robots.swift
class Point {
  var x: Int
  var y: Int

  init(x: Int, y: Int) {
    self.x = x
    self.y = y
  }
}

class Machine {
  var location: Point

  init() {
    self.location = Point(x: 0, y: 0)
  }

  func move(_ direction: String) {
    print("Do nothing! I am a machine!")
  }
}

// Enter your code below

class Robot: Machine {

    override func move(_ direction: String) {
        switch direction {
        case "Up":
            location.y += 1
        case "Down":
            location.y -= 1
        case "left":
            location.x -= 1
        case "right":
            location.x += 1
        default:
           break
        }
    }

}

The switch is correct, only problem is that you have typed "left" and "right" the wrong way according to the challenge. They should start with capital letters, thats it.
