[SwiftUI] Slider text is not appearing at all

The sliders themselves are rendered, but not the text no matter what I try.

Here is my code for reference:

var body: some View {
        ScrollView {
            Text("Synth View")
                .font(.system(size: 55, weight: .semibold, design: .rounded))
                .padding(.bottom)
            VStack {
                Button(
                    "Trumpet",
                    action: {
                        modulatingMultiplier = 10
                        frequency = 200
                        carrierMod = 5
                        index = 440
                        amplitude = 10
                    }
                )
                
                LineGraph(data: data, maxData: maxData, minValue: graphMinValue, maxValue: graphMaxValue)
                    .clipped()
                    .background(Color.accentColor.opacity(0.1))
                    .cornerRadius(20)
                    .padding()
                    .aspectRatio(1, contentMode: .fit)
                
                
                VStack {
                    Slider(value: $frequency, in: 0...20000) {
                        Text("Frequency").padding(.horizontal)
                    }
                    Slider(value: $modulatingMultiplier, in: 0...1000) {
                        Text("Modulating Multiplier").padding(.horizontal)
                    }
                    Slider(value: $carrierMod, in: 0...1000) {
                        Text("Carrier Mod").padding(.horizontal)
                    }
                    Slider(value: $amplitude, in: 0...1000) {
                        Text("Amplitude").padding(.horizontal)
                    }
                    Slider(value: $index, in: 0...1000) {
                        Text("Modulation Index").padding(.horizontal)
                    }
                }.padding(.horizontal).frame(width: 600)
            }
            .onAppear {
                detector.onUpdate = {
                    data.append(Double(detector.pitch) * 0.01)
                    detector.setFrequency(Frequency : frequency, modulatingMultiplier : modulatingMultiplier, Amplitude: amplitude, cMult : carrierMod, index : index)
                }
            }
        }
    }
