Photon2 billboards take a long time to face the camera

Question

I'm using PUN2 and trying to use nametag billboards for my players, but they are not facing forward correctly and I have to wait more than 20 seconds to make the name tag of player return to facing forward.

here's my code for my BillBoard Script:

public class BillBoard : MonoBehaviour
{
    protected Transform ThisCameraPlayerBillBoard ;


    private void Start()
    {
        ThisCameraPlayerBillBoard = GameSetup.GS.ThisCameraToBillBoard.GetComponent<Camera>().transform;

    }

    private void FixedUpdate()
    {
        transform.LookAt(transform.position + ThisCameraPlayerBillBoard .rotation * Vector3.forward,
            ThisCameraPlayerBillBoard .rotation * Vector3.up);
    
    }
}
