C＃项目帮助

嘿那里！我在使用这段代码时遇到了麻烦： 

Hey there! I'm  having trouble with this bit of code: 

它应该做的是将数字更新为数组，然后与unity pre-fabs一起使用以生成地图。它似乎忽略了更新数组的4和5的代码，我想知道是否有人知道为什么？

What it's supposed to do is update numbers to an array thats then used with unity pre-fabs to generate a map. it seems to be ignoring the code that updates 4's and 5's to the array, i was wondering if anyone knows why?

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




public class MapCreate : MonoBehaviour {

public int[,] GridArray = new int[30, 50];
public int rows = 30;
