[Bug?] Config files not always updating

I’m still blocking on this problem, this time for registering a binding. No matter what Key I try to register. I even tried to remove the full config folder in the saved folder of my project, it doesn’t change anything.

[Engine.PlayerInput]
+ActionMappings=(ActionName="Jump", Key=SpaceBar)
+ActionMappings=(ActionName="Jump", Key=XboxTypeS_A)
+ActionMappings=(ActionName="exitgame", Key=Escape)

and

void AEXILCharacter::SetupPlayerInputComponent(class UInputComponent* InputComponent)
{
	Super::SetupPlayerInputComponent(InputComponent);

	BIND_ACTION(InputComponent, "Jump", IE_Pressed, &AEXILCharacter::OnStartJump);
	BIND_ACTION(InputComponent, "Jump", IE_Released, &AEXILCharacter::OnStopJump);
	
	BIND_ACTION(InputComponent, "exitgame", IE_Pressed, &AEXILCharacter::ExitGame);
	BIND_ACTION(InputComponent, "exitgame", IE_Released, &AEXILCharacter::ExitGame);
}

void AEXILCharacter::ExitGame()
{
	elog("Exit");
}

My log function is never called. It’s starting to be very annoying to work. :'|
