Wrong Ordered List Export

[OscarXChen]

Describe the bug
When exporting the ordered list on Onenote to a Markdown file, some sequence tables may not be correctly recognized, such as the following format:
1.[text1]
\tab a.[text2]
\tab [text3]
\tab b.[text4]

Sometimes can be wrong like:
1.[text1]
\tab a.[text2]
\tab [text3]
2.[text4]

We can find that [text4] has wrong ordered list.

Desktop (please complete the following information):

• OneNodeMdExporter version : v1.4.0
• Windows version : win10 64
• Office Version : office 2019

错误的有序列表导出

Onenote上的有序列表导出到Markdown文件时，部分有序列表无法正确识别，例如以下格式：

1.[text1]
\tab a.[text2]
\tab [text3]
\tab b.[text4]

有时变为：
1.[text1]
\tab a.[text2]
\tab [text3]
2.[text4]

可见[text4]的有序列表信息发生错误

Thank you the issue. It would be great if you can join a sample onenote notebook to reproduce the bug.
