Unity 2D Game Moving with Animations

Question

I'm building a 2D Unity Game in C#. I made some Animations for the movements, but the Animation for the left movements doesn't work. The Player is moving to the left, but the Animation from the right-movement is displayed.

Here is my Movement-Code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Player : MonoBehaviour
{

private BoxCollider2D boxCollider;
private Vector3 moveDelta;
private RaycastHit2D hit;


// Start is called before the first frame update
void Start()
{
    boxCollider = GetComponent<BoxCollider2D>();
}

// Update is called once per frame
void FixedUpdate() // wichtig, wenn der Körper schaden nimmt
{
   
    float x = Input.GetAxisRaw("Horizontal");
    float y = Input.GetAxisRaw("Vertical");

     //Reset MoveDate
    moveDelta = new Vector3(x,y,0);

    //Nach rechts & links gehen

    if(moveDelta.x > 0)
        transform.localScale = Vector3.one;
    else if(moveDelta.x < 0)
        transform.localScale = new Vector3(-1,1,1);
    //Lässt uns dahin bewegen, indem wir eine Box erstellen. Gibt die null zurück, können wir uns bewegen
    hit = Physics2D.BoxCast(transform.position,boxCollider.size, 0, new Vector2(0,moveDelta.y), Mathf.Abs(moveDelta.y * Time.deltaTime), LayerMask.GetMask("Blocking","Humans"));

    if(hit.collider == null){
        // Bewegung
    transform.Translate(0, moveDelta.y * Time.deltaTime, 0);

    }

    hit = Physics2D.BoxCast(transform.position,boxCollider.size, 0, new Vector2(moveDelta.x,0), Mathf.Abs(moveDelta.x * Time.deltaTime), LayerMask.GetMask("Blocking","Humans"));

    if(hit.collider == null){
        // Bewegung
    transform.Translate(moveDelta.x * Time.deltaTime, 0, 0);

        }

    }
}

I animated the Animations seperatly (up,down,right,left) in an Animator, where all the animations are combined in an Blend Tree. Every other movement works fine inkl. the right Animations, except the fact that my player is moving to the left, but the Animation is like he would wolk right...

What did i do wrong?
