Docx file not getting converted to epub with table of contents

[archz2]

I am trying to convert an msword docx file to an epub.

The word file has auto-generated headings section. So I want those headings to read as table of contents.

However, only 4 headings are coming out in the clickable table of contents that shows up on the left in the calibre reader, as well as in the Kindle viewer.

What should I do?

Here's what the word file looks like with the headings.

Here's how the headings are coming out in the table of contents of the resultant epub file.

I didn't do any specific settings in the docx file.

I am enclosing both the source docx file and resultant epub file.

What happens if you re-add the docx to calibre and try a conversion with default settings?

I'm asking because I converted with default settings and the ToC was fully generated.

Works for me with default settings
