Issue with camera manager ADS rotation

Hello, I am having an issue where the camera is rotating about the new location rather than the original location. Basically I am making a true FPS style camera location from the head socket and VInterpTo the new location of the “gun” (currently using a torus-like mesh as a placeholder). In the normal state it works fine, but when I zoom in, it starts to rotate from the new point instead of from the head.

Code:

void AShooterCameraManager::UpdateViewTarget(FTViewTarget& OutVT, float DeltaTime) {
  Super::UpdateViewTarget(OutVT, DeltaTime);

  ABasePlayerController* ShooterController = Cast<ABasePlayerController>(GetOwningPlayerController());
	if (ShooterController != nullptr) {
    AShooterCharacter* Character = Cast<AShooterCharacter>(ShooterController->GetViewTarget());

    if (Character != nullptr && Character->GetAbilitySystemComponent()) {
      // Standard Camera Management
      float Pitch = GetOwningPlayerController()->GetControlRotation().Pitch;
      if (Pitch > 90.f)
      {
        // map pitch from [270, 360) to [-90, 0)
        FVector2D InRange(270.f, 360.f);
        FVector2D OutRange(-90.f, 0.f);
        Pitch = FMath::GetMappedRangeValueClamped(InRange, OutRange, Pitch);
      }
      float Yaw = GetOwningPlayerController()->GetControlRotation().Yaw;

      FRotator ControlRot = FRotator(Pitch, Yaw, GetOwningPlayerController()->GetControlRotation().Roll);

      //OutVT.POV.Rotation = ControlRot;

      // Set default target location
      TargetLocation = Character->GetMesh()->GetSocketLocation(FName("head"));
      TargetRotation = ControlRot;
      
      // ADS Camera Management
      if (Character->GetAbilitySystemComponent()->GetTagCount(ShooterGameplayTags::Abilities_ADS) == 1) {
        TargetLocation = Character->GetGunComponent()->GetSocketLocation(FName("Muzzle")) - FVector(20.0f, 10.0f, 0.f);
      }

      if (!bInterpolating) {
        bInterpolating = true;
        StartLocation = OutVT.POV.Location;
        StartRotation = OutVT.POV.Rotation;
      }

      // Interpolate between StartLocation and TargetLocation
      FVector NewLocation = FMath::VInterpTo(OutVT.POV.Location, TargetLocation, DeltaTime, InterpolationSpeed);
      // Update camera location
      OutVT.POV.Location = NewLocation;

      // Interpolate between StartRotation and TargetRotation
      FRotator NewRotation = FMath::RInterpTo(OutVT.POV.Rotation, TargetRotation, DeltaTime, InterpolationSpeed);


      // Update camera rotation
      OutVT.POV.Rotation = NewRotation;

      // Check if interpolation is complete
      if (NewLocation.Equals(TargetLocation, 1.0f)) {
          bInterpolating = false;
      }

This is the photo of the original state, which works
