My Picker retuns to the wrong view. I'm following along the iDine tutorial and after selecting my payment type, it retuns to the Order View, instead of the Checkout View where it came from... Any thoughts / help?

Here's a screen capture. iCloud Drive Link

Using Xcode 13 (beta 2) SwiftUI 3

var body: some View {
        Form {
            Section {
                Picker("How do you want to pay?", selection: $paymentType) {
                    ForEach(paymentTypes, id: \.self) {
                        Text($0)
                    }
                }

                Toggle("Add Loyalty Card #", isOn: $addLoyaltyDetails.animation())
                if addLoyaltyDetails {
                    TextField("Enter your loyalty #", text: $loyaltyNumber)
                }

            }

            Section(header: Text("Add a Tip??")) {
                Picker("Tip Percentage:", selection: $tipAmount) {
                    ForEach(tipPercentages, id: \.self) {
                        Text("\($0)%")
                    }
                }.pickerStyle(.segmented)
            }

            Section(header:
                        Text("Total: \(totalPrice)")
                        .font(.largeTitle)
            ) {
                Button("Confirm Order") {
                    showingPaymentAlert.toggle()
                }
            }
        }
        .navigationTitle("Payment")
        .navigationBarTitleDisplayMode(.inline)
        .alert(isPresented: $showingPaymentAlert) {
            Alert(title: Text("Order Confirmed"), message: Text("Your total was \(totalPrice)"), dismissButton: .default(Text("OK")))
        }
    }
