Wrong Scene loading from Pause

When I am in Pause state, and click on the Resume to Level button, instead of it going to the game, it goes to the main menu. No matter what number I type in the parentheses. The code and picture follows: using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.SceneManagement;

public class PauseGame : MonoBehaviour { public bool gamePaused = false; public AudioSource levelMusic; public GameObject pauseMenu; public AudioSource pauseJingle;

 void Update()
 {
     if (Input.GetButtonDown("Cancel"))
     {
         if(gamePaused == false)
         {
             pauseJingle.Play();
             Time.timeScale = 0;
             gamePaused = true;
             Cursor.visible = true;
             levelMusic.Pause();
             pauseMenu.SetActive(true);                
         }
         else
         {
             pauseMenu.SetActive(false);
             levelMusic.UnPause();
             Cursor.visible = false;
             gamePaused = false;
             Time.timeScale = 1;                
         }
     }
 }
 public void ResumeGame()
 {
     pauseMenu.SetActive(false);
     levelMusic.UnPause();
     Cursor.visible = false;
     gamePaused = false;
     Time.timeScale = 1;
 }

 public void RestartLevel()
 {
     pauseMenu.SetActive(false);
     levelMusic.UnPause();
     Cursor.visible = false;
     gamePaused = false;
     Time.timeScale = 1;
     SceneManager.LoadScene(3);![alt text][1]
