如何去除Plotly漏斗图中的异常涂鸦？

我尝试调整字体、文本位置（内部/外部）及其他格式选项，但均未解决问题，甚至不清楚这些异常涂鸦是什么。

import plotly.graph_objs as go
import pandas as pd

marketing_funnel_count = marketing_funnel_count.sort_values('FUNNEL_EVENT_COUNT', ascending=False)

# 计算各阶段的百分比变化
marketing_funnel_count['Percent Change'] = [100.0] + [(marketing_funnel_count['FUNNEL_EVENT_COUNT'][i] / marketing_funnel_count['FUNNEL_EVENT_COUNT'][i-1]) * 100 for i in range(1, len(marketing_funnel_count))]

# 创建漏斗图
fig = go.Figure(go.Funnel(
    y=marketing_funnel_count['FUNNEL_EVENT'],
    x=marketing_funnel_count['FUNNEL_EVENT_COUNT'],
    textposition='inside',
    textinfo='percent previous',
    marker=dict(color=['#FFD700', '#C0C0C0', '#CD7F32', '#800000', '#FFD700', '#C0C0C0']),
    connector=dict(line_color='rgba(0,0,0,0)', line_width=0.1),
    connector_visible=False,
    showlegend=False))

# 添加百分比变化注释
for i in range(len(marketing_funnel_count)):
    fig.add_annotation(x=marketing_funnel_count['FUNNEL_EVENT_COUNT'][i], y=marketing_funnel_count['FUNNEL_EVENT'][i],
                       text=f'{marketing_funnel_count["Percent Change"][i]:.1f}%',
                       showarrow=False)

# 展示图表
fig.show()
