Plotly: Sunburst plot missing sections

When plotting data using plotly.graph_object sunburst some labels are missing when compared to same data plotted with plotly.express sunburst

Plot missing the outermost sections:

Data is still there because when expanded it the data moves from other parents to their intended place

Graph showing the motion of the data:

you can see "btnCancel" moving over from "dlgMessageBox" to "frmRibbonConfigureOffsets"

Here is same data plotted with express:

Code used:

    # results is a pandas dataframe after some formatting and data analysis
    # extract needed data to form a list data
    p = results["Parent Name"] .to_list()
    n = results["Control Name"].to_list()
    c = results["Count"]       .to_list()
    # parents requiere "" parents with 0 val, but can't have duplicates
    pRed = results["Parent Name"].drop_duplicates().to_list()
    
    # make plot grid and set plot types acordingly
    fig = subplots.make_subplots(rows=1, cols=2, specs=[[{"type": "pie"}, {"type": "pie"}]])
    fig.add_sunburst(
        parents = ["" for _ in pRed] + p,   # parent list, parents of parents are ""
        labels  =              pRed  + n,   # data lable list
        values  = [ 0 for _ in pRed] + c,    # values, parents have 0
        row=1, col=1
    )
    # this second plot is to be replaced by a different type of plot later
    fig.add_sunburst(
        parents = ["" for _ in pRed] + p,   # parent list, parents of parents are ""
        labels  =              pRed  + n,   # data lable list
        values  = [ 0 for _ in pRed] + c,    # values, parents have 0
        row=1, col=2
    )
    # show plots
    fig.show()
    # express plot for comparasin
    expressPlot = px.sunburst(
        results,
        path=[ "Parent Name", "Control Name" ],
        values="Count"
    )
    expressPlot.show()

Any other formatting of the data passed to the labels/parents results in empty plots
