iTween makes a weird start on the path

I've been working with iTween and got the basics down, so maybe I'm overlooking something.

My code is pretty simple, I'm using the Itween graphic interface.

 using UnityEngine;
 using System.Collections;
 
 public class Trayectoria_Leo : MonoBehaviour {
 
     // Use this for initialization
     void Start () {
         iTween.Init(gameObject);
     }
     
     // Update is called once per frame
     void Update () {
 
         if (Input.GetKey(KeyCode.Space))
         {
             iTween.MoveTo(gameObject, iTween.Hash("path", iTweenPath.GetPath("Trayectoria"), "time", 10, "easetype", iTween.EaseType.linear, "delay", 1.5));
         }
     }
 }

This works perfectly and it's a simple three nodes path, but then at the start the object instead of instantly following the path like it's supposed to, crawls back a lot and then starts moving along the path. I don't know if it's a kind of ease in or something. It strikes me as odd since the starting node is at the origin of the object.

Thanks in advance for your help. Dragonliger PS. if you need I can get a screenshot of the problem.
