Canvas moves faster the second time it goes somewhere in the scene

I have 2 canvases in a scene. The second one is meant to come over the first, then leave. The first time it comes it moves slower than when it leaves or comes again any other time. The speed should not change anywhere in the code. I am curious about this behaviour, so if anyone could enlighten me please do it. Here is the code and a gif of the situation.

 using System;
 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 
 public class MainMenuNavigator : MonoBehaviour
 {
     [Header("Canvases")]
     [SerializeField] private Canvas _menuCanvas;
     [SerializeField] private Canvas _optionsCanvas;
     [SerializeField] private Canvas _profilesCanvas;
 
     [Header("Canvas movement options")]
     [SerializeField] private float _moveSpeed = 100f;
     [SerializeField] private Transform _destination;
     [SerializeField] private Transform _hidingPlace;
 
     [Header("Menu components")]
     [SerializeField] private Button[] _menuButtons;
     [SerializeField] private Button[] _optionsButtons;
     [SerializeField] private Button[] _profilesButtons;
 
     private Canvas _activeCanvas;
 
     private void Start()
     {
         _activeCanvas = _menuCanvas;
         
         ToggleButtons(_optionsButtons);
         ToggleButtons(_profilesButtons);
     }
 
     public void SwitchToMenu()
     {
         StartCoroutine(MoveCanvas(_activeCanvas, _hidingPlace.position));
         ToggleButtons(_activeCanvas == _optionsCanvas ? _optionsButtons : _profilesButtons);
         _activeCanvas = _menuCanvas;
         ToggleButtons(_menuButtons);
     }
 
     public void SwitchToOptions()
     {
         ToggleButtons(_menuButtons);
         StartCoroutine(MoveCanvas(_optionsCanvas, _destination.position));
         ToggleButtons(_optionsButtons);
         _activeCanvas = _optionsCanvas;
     }
 
     public void SwitchToProfiles()
     {
         ToggleButtons(_menuButtons);
         StartCoroutine(MoveCanvas(_profilesCanvas, _destination.position));
         ToggleButtons(_profilesButtons);
         _activeCanvas = _optionsCanvas;
     }
 
     private IEnumerator MoveCanvas(Canvas canvas, Vector3 newPosition)
     {
         while (!canvas.transform.position.Equals(newPosition))
         {
             canvas.transform.position =
                 Vector3.MoveTowards(canvas.transform.position, newPosition, _moveSpeed * Time.deltaTime);
             yield return null;
         }
     }
     
     private void ToggleButtons(IEnumerable<Button> buttons)
     {
         foreach (var button in buttons)
         {
             button.enabled = !button.enabled;
         }
     }
 }
