Code generating 2 different results?

Questions & Answers

Not sure why, its working when I use one set of variables, but not the other.

Screenshots of results and code: Unity, Same code generating different results - Album on Imgur

 void Start()
    {
        board = GetComponentInChildren<Transform>().gameObject;

        int[] sizeSpaces = { Mathf.FloorToInt(boardSize.x), Mathf.FloorToInt(boardSize.y) };

        boardPieces = new GameObject[sizeSpaces[0],sizeSpaces[1]];
        
        for (int j = 0; j < boardSize.y; j=j+1)
        {
            for(int i = 0; i < boardSize.x; i=i+1)
            {
                Debug.Log("" + i + "," + j);
                boardPieces[i,j] = GameObject.Instantiate(
                    boardPiece, 
                    new Vector3(
                        (-boardSize.x / 2) + i +.5f, 
                        0.15f, (-boardSize.x / 2) + j + .5f),
                    new Quaternion(0,0,0,0), 
                    this.transform);
            }
        }
    }

Issue solved.

void Start()
    {
        board = GetComponentInChildren<Transform>().gameObject;

        sizeSpaces = new int[]{ Mathf.FloorToInt(boardSize.x), Mathf.FloorToInt(boardSize.y) };

        boardPieces = new GameObject[sizeSpaces[0],sizeSpaces[1]];
        
        for (int j = 0; j < boardSize.y; j=j+1)
        {
            for(int i = 0; i < boardSize.x; i=i+1)
            {
                Debug.Log("" + i + "," + j);
                boardPieces[i,j] = GameObject.Instantiate(boardPiece, this.transform);
                boardPieces[i, j].transform.localPosition = new Vector3(Mathf.Ceil(-boardSize.x / 2 + i), .15f, Mathf.Ceil(-boardSize.y / 2 + j));
            }
        }
    }
