Platform Collider Not Working When Enemy Collides With It

So, I have this infinite runner / platformer game in which I generate an enemy on a platform. The platforms have 2 enemy colliders that is supposes to collide with the enemy, but my enemies just go past the colliders. My 2 colliders (left and right collider) are a child of my platforms. My platforms are generate using a script that is attached to my first platform.

Enemy.cs Script

 using UnityEngine;
 
 public class Enemy : MonoBehaviour {
 
     private SpriteRenderer sp;
 
     private float disMax;
     private float disMin;
     private float dis; // Distance travel / frame
 
     private void Start() {
 
         sp = GetComponent<SpriteRenderer>();
         
         PickDis();
         Flip();
 
     }
 
     private void Update() {
 
         Move();
 
     }
 
     /// <summary>
     /// Makes enemy move
     /// </summary>
 
     private void Move() {
 
         float x = transform.position.x + dis * Time.deltaTime;
         transform.position = new Vector3(x, transform.position.y, transform.position.z);
 
     }
 
     /// <summary>
     /// Picks a random distance / frame
     /// </summary>
 
     private void PickDis() {
 
         disMin = -1f;
         disMax = 1f;
 
         float rand = 0f;
 
         while(rand == 0f) {
             rand = Random.Range(disMin, disMax);
         }
 
         dis = rand;
 
     }
 
     private void Flip() {
 
         if (dis > 0f) {
             // Right
             sp.flipX = true;
         } else if (dis < 0f) {
             // Left
             sp.flipX = false;
         }
 
     }
 
 }

Platform Generator Script

 using UnityEngine;
 
 public class GeneratePlatforms : MonoBehaviour {
 
     public static GeneratePlatforms Instance = null;
 
     [SerializeField] private GameObject platform;
 
     private SpriteRenderer sp;
 
     private Camera cam; // Main camera
     private float camHeight; // Height of the camera view port
     private Vector2 currentPos; // Last platforms position
 
     private int maxPlatforms; // Maximum number of platforms
 
     // Min and max height range for generating platforms
     private float yMin;
     private float yMax;
 
     // Min and max scale range for width
     private float scaleWMin;
     private float scaleWMax;
 
     private float gap; // Gap between each platform
     private float w; // Width of the platform object
 
     private void Start() {
 
         sp = GetComponent<SpriteRenderer>();
         
         cam = Camera.main;
         camHeight = 2 * cam.orthographicSize;
         currentPos = transform.position;
 
         maxPlatforms = 20;
         
         yMin = (-camHeight / 2) + 0.8f;
         yMax = (camHeight / 2) - 3f;
 
         scaleWMin = 0.05f;
         scaleWMax = 0.14f;
 
         gap = 7f;
         w = sp.bounds.size.x;
 
         if (Instance == null) {
             Instance = this;
         } else if (Instance != this) {
             Destroy(gameObject);
         }
 
         Generate(maxPlatforms);
 
     }
 
     /// <summary>
     /// Generates max number of platforms on start
     /// </summary>
     /// <param name="max">Max number of platforms to generate</param>
 
     public void Generate(int max) {
 
         for (int i = 0; i < max; i++) {
             float randomY = Random.Range(yMin, yMax);
             float randomScaleW = Random.Range(scaleWMin, scaleWMax);
 
             // Up
             if (randomY > currentPos.y + 3f) {
                 gap = 10f;
             }
 
             // Down
             if (randomY < currentPos.y - 4f) {
                 gap = 5f;
             }
 
             float x = (currentPos.x + w) + gap;
             Vector2 lastPos = new Vector2(x, randomY);
 
             GameObject newPlatform = Instantiate(platform, lastPos, Quaternion.identity);
 
             newPlatform.transform.localScale = new Vector3(randomScaleW, newPlatform.transform.localScale.y, newPlatform.transform.localScale.z);
 
             currentPos = lastPos;
         }
 
     }
 
 }
