Animation Won't Loop (But others will)

As stated in the title, I just simply can't get my animation to loop (but others will). Basically, I'm very new to unity and I'm trying to learn unity to create my first game, so I have to start with the character. After a few hours of research and following some tutorials, I think I got a pretty good setup for my character. The only thing is, I want my character to be able to strafe left and right and whenever he strafes left, he just stays in the final frame. I have already looked up many many solutions to no prevail and I have also checked that both, "Loop Time" and "Loop Pose" are both checked on. As I said, I am new to Unity so this is my first script that I am using so please don't judge too hard (some code is directly off of tutorials while some aren't).

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Controller : MonoBehaviour {
 
     public float runSpeed = 2;
     public float walkSpeed = 10;
     public float rotateSpeed = 0.5f;
     public float jumpSpeed = 6;
     public float gravity = 20f;
 
     private Vector3 moveDirection = Vector3.zero;
     private CharacterController controller;
 
     private Animator animator;
 
 
     // Use this for initialization
     void Start () {
         controller = GetComponent<CharacterController>();
         animator = GetComponent<Animator>();
     }
     
     // Update is called once per frame
     void Update () {
         moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
         moveDirection = transform.TransformDirection(moveDirection);
 
         bool running = Input.GetKey(KeyCode.LeftShift);
         if (running)
         {
             moveDirection *= runSpeed;
         }
         else {
             moveDirection *= walkSpeed;
         }
        
 
 
 
         moveDirection.y -= gravity * Time.deltaTime;
         controller.Move(moveDirection * Time.deltaTime);
 
 
         bool walkingForward = Input.GetKey("w");
         float animationForward = ((walkingForward) ? 1 : 0);
         animator.SetFloat("Input Z", animationForward);
 
         bool strafeLeft = Input.GetKey("a");
         float animationLeft = ((strafeLeft) ? 1 : 0);
         animator.SetFloat("Input X", animationLeft);
 
 
         
 
         if (!walkingForward && !strafeLeft)
         {
             animator.SetFloat("Input X", 0);
             animator.SetFloat("Input Z", 0);
         }
 
 
 
     }
 }
