Audio options "%" won't update till slider is moved

Hi,

I’m currently designing my games Options and have finalized my Audio sliders. My Issue though is in the TMP field for the text I have input xxx% as a placeholder with this script attached:

public class AudioController : MonoBehaviour
{
    public string VolumeType = "Volume";
    public AudioMixer Mixer;
    public Slider Slider;
    public TextMeshProUGUI VolumeText;
    public float Multiplier = 30f;
    [Range(0,1)] public float DefaultSliderPercentage = 0.75f;

    private void Awake()
    {
        if(!PlayerPrefs.HasKey(VolumeType))
        {
            PlayerPrefs.SetFloat(VolumeType, DefaultSliderPercentage);
        }
        Slider.onValueChanged.AddListener(SliderValueChanged);

        Slider.value = PlayerPrefs.GetFloat(VolumeType);
    }

    public void SliderValueChanged(float sliderValue)
    {
        Mixer.SetFloat(VolumeType, SliderToDecibel(sliderValue));
        VolumeText.text = Mathf.Round(sliderValue * 100) + "%";

        PlayerPrefs.SetFloat(VolumeType, sliderValue);
        PlayerPrefs.Save();
    }

    private float SliderToDecibel(float value)
    {
        return Mathf.Clamp(Mathf.Log10(value/DefaultSliderPercentage) * Multiplier, -80f, 20f);
    }
}

My problem is that when starting the game the text shows as “xxx%” until i move the slider which then updates correctly. How do i make it show the correct number when starting the game?

I’ve found out it only shows xxx% if the number is slider is maxed out at 100%. Still unsure on how to fix this.
