Question Cinemachine is sometimes rotating too fast

I'm kind of new to Unity, and I'm trying to make a 3rd person and 1st person camera. The cameras were rotating fine before, but right now for some reason they are rotating too fast sometimes even though I didn't change anything in the scripts. Here is the script and the components:

Code (CSharp):

1. using UnityEngine;
2. using Cinemachine;
3.  
4. public class CameraController : MonoBehaviour
5. {
6.     [SerializeField] HumanoidLandInput _input;
7.  
8.     [SerializeField] float _cameraZoomModifier = 32.0f;
9.  
10.     float _minCameraZoomDistance = 1.125f;
11.     float _maxCameraZoomDistance = 3.0f;
12.  
13.     CinemachineVirtualCamera _activeCamera;
14.     int _activeCameraPriorityModifer = 31337;
15.  
16.     public Camera MainCamera;
17.     public CinemachineVirtualCamera cinemachine1stPerson;
18.     public CinemachineVirtualCamera cinemachine3rdPerson;
19.     CinemachineFramingTransposer _cinemachineFramingTransposer3rdPerson;
20.  
21.     private void Awake()
22.     {
23.         _cinemachineFramingTransposer3rdPerson = cinemachine3rdPerson.GetCinemachineComponent<CinemachineFramingTransposer>();
24.     }
25.  
26.     private void Start()
27.     {
28.         ChangeCamera(); // First time through, lets set the default camera.
29.     }
30.  
31.     private void Update()
32.     {
33.         if (!(_input.ZoomCameraInput == 0.0f)) { ZoomCamera();  }
34.         if (_input.ChangeCameraWasPressedThisFrame) { ChangeCamera(); }
35.     }
36.  
37.     private void ZoomCamera()
38.     {
39.         if (_activeCamera == cinemachine3rdPerson)
40.         {
41.             _cinemachineFramingTransposer3rdPerson.m_CameraDistance = Mathf.Clamp(_cinemachineFramingTransposer3rdPerson.m_CameraDistance +
42.                                 (_input.InvertScroll ? _input.ZoomCameraInput : -_input.ZoomCameraInput) / _cameraZoomModifier,
43.                                 _minCameraZoomDistance,
44.                                 _maxCameraZoomDistance);
45.         }
46.     }
47.  
48.     private void ChangeCamera()
49.     {
50.         if (cinemachine3rdPerson == _activeCamera)
51.         {
52.             SetCameraPriorities(cinemachine3rdPerson, cinemachine1stPerson);
53.             MainCamera.cullingMask &= ~(1 << LayerMask.NameToLayer("Player (Self)"));
54.         }
55.         else if (cinemachine1stPerson == _activeCamera)
56.         {
57.             SetCameraPriorities(cinemachine1stPerson, cinemachine3rdPerson);
58.             _activeCamera = cinemachine3rdPerson;
59.             MainCamera.cullingMask |= 1 << LayerMask.NameToLayer("Player (Self)");
60.         }
61.         else // for first time through or if there's an error
62.         {
63.             cinemachine3rdPerson.Priority += _activeCameraPriorityModifer;
64.             _activeCamera = cinemachine3rdPerson;
65.         }
66.     }
67.  
68.     private void SetCameraPriorities(CinemachineVirtualCamera CurrentCameraMode, CinemachineVirtualCamera NewCameraMode)
69.     {
70.         CurrentCameraMode.Priority -= _activeCameraPriorityModifer;
71.         NewCameraMode.Priority += _activeCameraPriorityModifer;
72.         _activeCamera = NewCameraMode;
73.     }
74. }
