Remember, if you are using UE4 4.23 or higher, the motion source uses FStrings instead of the Enum states. I had to change my code as follows:

HandControllerBase.h
public:
virtual void TriggerPressed() {}
virtual void TriggerReleased() {}
void SetHand(FString Hand);

HandControllerBase.cpp
void AHandControllerBase::SetHand(FString Hand)
{
if (Hand == “Left”) {
MotionController->SetTrackingMotionSource(“EControllerHand::Left”);
}
else if (Hand == “Right”) {
MotionController->SetTrackingMotionSource(“EControllerHand::Right”);
}
}

VRPawn.cpp
void AVRPawn::BeginPlay()
{
Super::BeginPlay();

if (RightHandControllerClass) {
	RightHandController = GetWorld()->SpawnActor<AHandControllerBase>(RightHandControllerClass);
	RightHandController->AttachToComponent(GetRootComponent(), FAttachmentTransformRules::SnapToTargetIncludingScale);
	RightHandController->SetHand("Right"); //Use FString here instead of Enum
	RightHandController->SetOwner(this); //SetOwner must be included for 4.23 or higher
}

if (LeftHandControllerClass) {
	LeftHandController = GetWorld()->SpawnActor<AHandControllerBase>(LeftHandControllerClass);
	LeftHandController->AttachToComponent(GetRootComponent(), FAttachmentTransformRules::SnapToTargetIncludingScale);
	LeftHandController->SetHand("Left"); //Use FString here instead of Enum
	LeftHandController->SetOwner(this); //SetOwner must be included for 4.23 or higher
}

}

Both Controllers are spawning properly using the Enum - UE 4.26

void AVRPawn::BeginPlay()
{
	Super::BeginPlay();
	
	if (RightHandControllerClass)
	{
		RightHandController = GetWorld()->SpawnActor<AHandControllerBase>(RightHandControllerClass);
		RightHandController->AttachToComponent(GetRootComponent(), FAttachmentTransformRules::SnapToTargetIncludingScale);
		RightHandController->SetHand(EControllerHand::Right);
		RightHandController->SetOwner(this); // Set Owner UE4.20~

	}

	if (LeftHandControllerClass)
	{
		LeftHandController = GetWorld()->SpawnActor<AHandControllerBase>(LeftHandControllerClass);
		LeftHandController->AttachToComponent(GetRootComponent(), FAttachmentTransformRules::SnapToTargetIncludingScale);
		LeftHandController->SetHand(EControllerHand::Left);
		LeftHandController->SetOwner(this); // Set Owner UE4.20~
	}
}
