Bar Graph Data Point incorrectly rendering

The data label for the 2nd of 3 bars in my bar chart is misrendering and I’m looking for assistance to get it fixed. Below is an image and the code:

#graph plot

    import plotly.plotly as py
    import plotly.graph_objs as go
    import plotly
    plotly.tools.set_credentials_file(username='bjpreisler', api_key='TnyV5yYf2ijrjWqEv0eu')

    trace1 = go.Bar(
        x=['Sept DMs','Current Month DMs', 'April Goal DMs'],
        y=[sept,current_DMs, goal_17],
        marker=dict(
            color=['rgb(55, 83, 109)', 'rgb(55, 83, 109)',
               'rgb(185,211,238)']),
    )

    x = ['Sept DMs','Current DMs', 'April Goal DMs']
    y = [sept,current_DMs,goal_17]
    data = [trace1]
    layout = go.Layout(
            annotations=[
            dict(x=xi,y=yi,
                 text=str(yi),
                 xanchor='center',
                 yanchor='bottom',
                 showarrow=False,
            ) for xi, yi in zip(x, y)],   

        title='%s DM Progress' %name,
        xaxis=dict(
            tickfont=dict(
                size=14,
                color='rgb(107, 107, 107)'
            )
        ),
        yaxis=dict(
            title='DM',
            titlefont=dict(
                size=16,
                color='rgb(107, 107, 107)'
            ),
            tickfont=dict(
                size=14,
                color='rgb(107, 107, 107)'
            )
        ),
        legend=dict(
            x=0,
            y=1.0,
            bgcolor='rgba(255, 255, 255, 0)',
            bordercolor='rgba(255, 255, 255, 0)'
        ),
        bargap=0.1,
        bargroupgap=0.3
    )


    fig = go.Figure(data=data, layout=layout)

    py.image.save_as(fig, filename= c[0] + '.png')

    from IPython.display import Image
