Duplicate plotly bar stack

📊 Plotly Python
1

Hi everyone, I have a dataset with two indexes but without any duplicates value. When I tried to plot this dataset as a bar chart like this:

      fig = go.FigureWidget(
          px.bar(
              data,
              x=data.index.get_level_values(0),
              y="Nb",
              text="Share",
              text_auto=True,
              color=data.index.get_level_values(1),
              color_discrete_map=fig_color(data.index.get_level_values(1).unique(), "id"),
              labels={
                  "x": input.compgap(),
                  "y": "Nb",
                  "color": input.compgap_level(),
              },
          ),
      )

Where input.compgap = data.index.get_level_values(0) (“…ment” on the screen below) and input.compgap_level = data.index.get_level_values(1) (-4.0 à 3.0 on the screen below).

I get this figure with this dataset:
Plotly_screen (2) Plotly_screen (1)

Do you know why rows are duplicated? Thanks all.
