Animation won't play just once and hold

I've been stuck on this for two days.

With this code:

  if (walkSpeed > 5 && Input.GetAxis("Mouse X") > 0)
             {
                 Animator animator = GetComponent<Animator>() as Animator;
                 animator.SetBool("Run_Turn_Right_A1_Bool", true);
             }
             else
             {
                 Animator animator = GetComponent<Animator>() as Animator;
                 animator.SetBool("Run_Turn_Right_A1_Bool", false);
             }

I start running and I move the mouse right. It triggers my bool properly.

But the animation the bool is connected to starts looping.

I can't get it to transition to anything, no matter what I do. I would like for it to play once and then stop on the last frame until the mouse isn't going to the right anymore.

Here's all the code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class ThridPersonCharacterController : MonoBehaviour
 {
     public float maxWalkSpeed = 10.0f;
     public float Speed;
 
     void Update () {
         float walkSpeed = Input.GetAxis("Vertical") * maxWalkSpeed;
         if (walkSpeed > 5)
         {
             Animator animator = GetComponent<Animator>() as Animator;
             animator.SetBool("Walk_A_Bool", false);
             animator.SetBool("Run_A_Bool", true);
 
         }
         else
         {
             Animator animator = GetComponent<Animator>() as Animator;
             animator.SetBool("Run_A_Bool", false);
         }
 
         if (walkSpeed >= 1 && walkSpeed <= 5)
         {
             Animator animator = GetComponent<Animator>() as Animator;
                animator.SetBool("Walk_A_Bool", true);
                 }
         else
         {
             Animator animator = GetComponent<Animator>() as Animator;
             animator.SetBool("Walk_A_Bool", false);
         }
 
         if (walkSpeed == 0 && Input.GetAxis("Mouse X") < 0)            
         {
             Animator animator = GetComponent<Animator>() as Animator;
             animator.SetBool("Stand_Turn_Left_A_Bool", true);
         }
         else { 
             Animator animator = GetComponent<Animator>() as Animator;
         animator.SetBool("Stand_Turn_Left_A_Bool", false);
                 }
 
         if (walkSpeed > 5 && Input.GetAxis("Mouse X") < 0)
         {
             Animator animator = GetComponent<Animator>() as Animator;
             animator.SetBool("Run_Turn_Left_A1_Bool", true);
         }
         else
         {
             Animator animator = GetComponent<Animator>() as Animator;
             animator.SetBool("Run_Turn_Left_A1_Bool", false);
         }
 
         if (walkSpeed > 5 && Input.GetAxis("Mouse X") > 0)
         {
             Animator animator = GetComponent<Animator>() as Animator;
             animator.SetBool("Run_Turn_Right_A1_Bool", true);
         }
         else
         {
             Animator animator = GetComponent<Animator>() as Animator;
             animator.SetBool("Run_Turn_Right_A1_Bool", false);
         }
 
         // if (walkSpeed == 0)
         // {
         //      Animator animator = GetComponent<Animator>() as Animator;
         //       animator.SetBool("Walk_A_Bool", false);
         //     }
 
 
         PlayerMovement(); 
     }
     void PlayerMovement()
     {
         float hor = Input.GetAxis("Horizontal");
         float ver = Input.GetAxis("Vertical");
         Vector3 playerMovement = new Vector3(hor, 0f, ver) * Speed * Time.deltaTime;
         transform.Translate(playerMovement, Space.Self);
     }
 }
 

Thanks.
