Power Bi Json Theme - Pivot Table Row Subtotal Formatting not working

Hi, I am creating a json Theme file for my company and I am stuck on the matrix table. It just doesnt take the inputs for row subtotals.

Here's the code:

{
    "name": "Test",
    "pivotTable": {
        "*": {
            "stylePreset": [
                {
                    "name": "Default"
                }
            ],
            "grid": [
                {
                    "gridVertical": false,
                    "gridHorizontal": false,
                    "rowPadding": 4,
                    "outlineWeight": 2,
                    "textSize": 10
                }
            ],
            "columnHeaders": [
                {
                    "fontColor": {
                        "solid": {
                            "color": "#ffffff"
                        }
                    },
                    "backColor": {
                        "solid": {

                        }

                            "color": "#0e1622"
                        }
                    },
                    "fontFamily": "Calibri",
                    "bold": true,
                    "applyToHeaders": true,
                    "applyToLabels": true,
                    "fontSize": 10
                }
            ]
        }
    }
}

When I load it into the report there's these two that don't do what I want (see attached pics):
- Column grand total needs to be Calibri 10, apply to labels true
- Row subtotals needs to also be Calibri 10,apply to labels true

I also included a pic of current vs desired. Please let me know what I did wrong!
