Header in word 2007 taking on wrong number values

[JGT]

I have a document that I've updated numerous times and the original document
was created several years ago in an earlier version of word (at this time I
have no idea what version of word was used). The main section of the document
starts of with using a heading level two and the heading is correctly
numbered as 1.1 the headings that follow seem to be OK until I get to page
21, in the middle of the page I've added a new heading level 3 and the number
appears as 4.1.1 whereas the previous heading level 3 (on page 18) is
numbered 1.1.2. There are no headings between the two headings and I only
have one section in the entire document. All of the headings that follow the
heading on page 21 seem to be in-sync with the heading on page 21. Between
the two headings I have a table with three columns where column 1 contains a
number to identify the row. Some of the rows either contain numbered list or
bullet list.

When viewing the TOC there are no headings between 1.1.1 and 4.1.1

How do I determine what the heading 4.1.1 is linked to and/or correct the
numbering issue, e.g. the heading should be numbered 1.1.3. I've tried
setting the number value but this did nothing for me.

OK I resolved the issue - the error was due to a number format used in the
table. The numbered items did NOT appear as headers and when I inspected the
style or formatting of the numbered items nothing I could see informed me
what the problem was. I removed the numbering and the problem disappeared.

I've resolved the issue but I don't know the cause.
