Blend tree flickering the first animation

Hi,

I have a problem with my blend tree. When my enemy is spawned, i have a code that moves the enemy towards my player.

using Pathfinding;
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEngine;

public class EnemyAi : MonoBehaviour
{
    private Transform player;

    Path path;
    int currentWaypoint = 0;
    bool reachedEndOfPath = false;
    public float speed = 200f;
    public float nextWaypointDistance = 3f;
    private Animator animator;
    private Vector2 moveDirection;

    Seeker seeker;
    Rigidbody2D rb;


    // Start is called before the first frame update
    void Start()
    {
        seeker = GetComponent<Seeker>();
        player = GameObject.FindWithTag("Player").transform;
        rb = GetComponent<Rigidbody2D>();
        animator = GetComponentInChildren<Animator>();

        InvokeRepeating("UpdatePath", 0f, .5f);
     
    }

    private void UpdatePath() {

        if (seeker.IsDone())
        {
            seeker.StartPath(rb.position, player.position, OnPathComplete);
        }
    }

    private void OnPathComplete(Path p)
    {
        if (!p.error) {
            path = p;
            currentWaypoint = 0;
        }
    }

    private void FixedUpdate()
    {
        if (path == null) return;

        if (currentWaypoint >= path.vectorPath.Count)
        {
            reachedEndOfPath = true;
            return;
        }
        else {
            reachedEndOfPath = false;
        }     

        Vector2 direction = ((Vector2)path.vectorPath[currentWaypoint] - rb.position).normalized;
        moveDirection = direction;
        Animate();

        Vector2 force = direction * speed * Time.deltaTime;


        rb.AddForce(force);

        float distance = Vector2.Distance(rb.position, path.vectorPath[currentWaypoint]);

        if (distance <= nextWaypointDistance) {
            currentWaypoint++;
        }
    }

    // Update is called once per frame
    void Update()
    {
      
    }

    private void Animate()
    {
        animator.SetFloat("velocityX", moveDirection.x);
        animator.SetFloat("velocityY", moveDirection.y);
    }
}

I set the parameters for my blend tree, but it looks like every second my blend tree resets to first animation for like a flicker and then plays animation correctly. Here is a gif of this happening. Why is this flickering happening?

Editing is having an error. I want to add that blend tree is for animation of enemy running.

Anyone knows why my blend tree resets to first animation every second? :frowning:
