Audio ByPassEffect seems to affect all audio sources

Hi !
I am trying to set up a pause menu where I apply a low pass filter on the audio when open.
The problem is that I want all audio sources to be under the filter effect EXCEPT the sound of the button's hover. In order to do that, I implement a script where I pick the correct audio source (the one that plays when I hover a button) and I enable the byPassEffect on this specific source:

public class AudioManager : MonoBehaviour{

Code (CSharp):

1. //Many other functions
2.  
3. public void ByPassEffect(string name)
4.     {
5.         Sound s = Array.Find(sounds, sound => sound.name == name);
6.         if (s == null)
7.         {
8.             Debug.LogWarning("Sound" + name + "not found !");
9.             return;
10.         }
11.         s.source.bypassEffects = true;
12.     }
13. }

Then I later call this function with:

Code (CSharp):

1. public class ButtonHover : MonoBehaviour
2. {
3.     private AudioManager audioManager;
4.  
5.     void Start()
6.     {
7.         audioManager = Object.FindObjectOfType<AudioManager>();
8.         audioManager.ByPassEffect("Hover");
9.     }
10.     public void Hover()
11.     {
12.         audioManager.Play("Hover");
13.     }
14. }

Everything seems to work properly: my filter is applied when I open my menu, my "Hover" source is not under the filter effect BUT the problem is that when I hover a button, all my sources seems to then have their byPassEffect value on true. The inspector shows empty tick boxes (except for the "Hover" source which is normal) but I can't hear the filter anymore..

The AudioManager is the one form Brackeys video (+ the homemade ByPassEffect function):

I have no idea why it behave like that, can anyone please help me ?

Thank you.
