The numbering of the headings does not follow

Good day,
using aspose, I got the document to a state where the numbering of the headings does not follow, I tried UpdateFields and UpdatePageLayout, but the numbers in the ms word application do not follow each other

Please look at the document to see if you can think of something how to display numbers one after the other.
If you want, I will send you the way I damaged the document. (I took it apart into sections and compared them to each other and reassembled them into one document)

Out.docx (4.6 MB)

@benestom As I can see paragraphs belongs to different lists. Most likely this happened upon splitting and reassembling the document. Please try using ImportFormatMode.UseDestinationStyles when join the parts of the document together. As I can see from the output document you have attached you used ImportFormatMode.KeepSourceFormatting.
