Adding to a List inside a Coroutine doesn't add properly?

Hey everyone,
I have a piece of code that can be simplified to this:

private List<List<int>> tempListListInt = new List<List<int>>();
    private List<int> tempListInt = new List<int>();

void Start()
    {
        StartCoroutine(TestListListInt());
    }

IEnumerator TestListListInt()
    {
        int tempInt;
        for (int i = 0; i < 10; i++)
        {
            tempListInt.Clear();
            yield return null;
            for (int j = 0; j < 10; j++)
            {
                tempInt = Random.Range(0, 10);
                tempListInt.Add(tempInt);
            }
            tempListListInt.Add(tempListInt);
        }
    }

when reading tempListListInt each List < int > stored inside is a copy of a List < int > tempListInt generated for i=9. I suppose I screwed something up with accessing global tempListListInt, but I am at loss as to what exactly. Help, pretty please?

Instead of List<List<int>> try using a class, like this

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

[System.Serializable]
public class IntList
{
    public List<int> list = new List<int>();
}
 
public class  : MonoBehaviour
{
    private List<IntList> tempListListInt = new List<IntList>();
    private IntList tempListInt = new IntList();

    void Start()
    {
        StartCoroutine(TestListListInt());
    }

    IEnumerator TestListListInt()
    {
        int tempInt;
        int total = 0;
        tempListListInt.Clear();
        for (int i = 0; i < 10; i++)
        {
            tempListInt.Clear();
            yield return null;
            for (int j = 0; j < 10; j++)
            {
                tempInt = Random.Range(0, 10);
                total += tempInt;
                tempListInt.list.Add(tempInt);
            }
            tempListListInt.Add(tempListInt);
        }
        yield return null;
        ShowListTotal(total);
    }

    // shows the total calculated in coroutine
    // and total from list
    void ShowListTotal(int total)
    {
        int tempTotal = 0;
        for (i = 0; i < tempListListInt.Count; i++)
        {
            for (j = 0; j < tempListListInt*.list.Count; j++)*

{
tempTotal += tempListListInt*.list[j];*
}
}
Debug.Log("Coroutine total equals " + total + ", list total equals " + tempTotal);
}
}
