I have a document with lots of tracked changes from multiple participants. I need to keep these changes tracked.

I am using a mulitlevel list (this is Word 2013) to create numbering on most of the paragraphs in the document,
i.e. they look like legal clauses and I need the numbering to restart automatically according to the number of the headings above. See example below:

6.1.1 Getting information

6.1.1.1 The assessor must get information about the following:

(a) time incident occurred
(b) place incident occurrred:

(i) home
(ii) work

6.1.1.2 The assessor must submit the information asap.

The above is just made up stuff to illustrate, note that the bold heading is the built in Word Heading 3 style,
clause number uses Heading 4 style, (a) is Heading 5 and (i) is Heading 6.
This is the best way I can think of to make all the clause and subclause numbers work correctly.

Anyhow, this is a big build-up to my actual problem: When I insert new clauses into the document, even with change tracking switched off,
Word seems to randomly track changes to some of the clause numbers in the document, e.g. 6.1.1.16.1.1.2 (imagine red is strike-out)

Not all changes to clause numbers are tracked, only some. The problem I have is that you can't seem to access this tracking to get rid of it.
If I jump from one change to another down the page, Word does not stop on these problematic changes.
Even if I select the whole paragraph and click Accept change the tracking won't go away.

This is annoying because the tracked change disrupts the layout of the clause and makes it look bad.
I don't want to send the document back to the client with some of the clauses all out of whack.

Anybody got any ideas? I tried a test version of the document where I accepted all changes and thankfully this unwanted
tracking disappeared, but I need to leave most of the change tracking on for now.

Thanks.
