Making pong! score problem

[hard wedge]

Hello! I'm creating a pong on my own and I have this issue with the score system.

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

public class leftScript : MonoBehaviour
{
    public int player2Score = 0;
    public Text score2;
    public bool ballAlive = true;

    public void addScore()
    {
        Debug.Log("Collision detected!");
        player2Score++;
        score2.text = player2Score.ToString();

    }
    private void OnCollisionEnter2D(Collision2D collision)
    {
        addScore();
        ballAlive = false;
    }

}

here is the code, I have colliders setup on left and right and each time ball hits them score increases respectfully. the porblem is:
at the start of the game score increases by 1 instantly for each player, after that it works perfectly fine

heres the setup

You don't check WHAT they collide with. The paddles immediately collide with the Left and Right collider walls

You have it so if ANYTHING collides, you add score
