Why I don't see the Dynamic methods in the On Value Changed () event/s ?

This is script is attached to a Canvas.

Code (csharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.Audio;
6.  
7. public class SettingsMenu : MonoBehaviour
8. {
9.    public AudioMixer audioMixer;
10.  
11.    public void SetVolume(float volume)
12.    {
13.        audioMixer.SetFloat("Volume", volume);
14.    }
15.  
16.    public void SetQuality(int qualityIndex)
17.    {
18.        QualitySettings.SetQualityLevel(qualityIndex);
19.    }
20. }
21.  

And then under it in the Hierarchy for example I have Graphics a DropDown ui. And on the Graphics in the Inspector at the bottom in On Value Changed I dragged the Canvas over but then when I click on No Function > SettingsMenu I can see the SetQuality method but there should be also SetQuality at the top under Dynamic int and it's not there :



Same problem with the SetVolume method. And I had this Dynamic float/int before but they are not exist now.

 

This implies the value passed in onvaluechanged doesn't or isn't gauranteed to match the function parameter datatype.

 

But it was working before. I saw the Dynamic int/float.
I don't understand what should I change/add in the script. I didn't change anything.

 

According to the docs onvaluechanged passes no parameter.

Look at the example below for an implementation

This may be a bug in your version of Unity
