Error when make the objects both MoveLeft and Spinning in Unity

I'm trying to make cts .

Here is the MoveLeft script:

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

public class MoveLeft : MonoBehaviour
{
    private float moveLeftSpeed = 10;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        transform.Translate(Vector3.left * Time.deltaTime * moveLeftSpeed);
    }
    
}

And there is the SpinObjects script:

using System.Collections.Generic;
using UnityEngine;

public class SpinObjectsX : MonoBehaviour
{
    public float spinSpeed = 50;

    // Update is called once per frame
    void Update()
    {
        transform.Rotate(new Vector3(0, Time.deltaTime * spinSpeed, 0));
    }
}

I expect the object's movement will look like this, it just moves to the left and spins itself.

But when I use both scripts, the object moves very weirdly, it is still spinning itself but instead of moving to the left, it spins around something...
