I work with many documents which are 50+ pages that include automatic
numbering and use Headers 1-4. On many occasions I have opened the document
to edit and the numbering has disappeared.
I have to go through to each level and at the header, select it, go to the
top menu bar where it says "Header x" hit enter and the numbering will start
there (starts over though and won't pick up if there is even one previous
header number). Thus for example if Header 1 is "5" and everything past "5"
is gone (in terms of numbering) I will go to level 2 which has Header 2 and
it hit enter and 1.1 appears.
I waste a lot of time renumbering long documents. Why does it do this and
more importantly is there a way to do a quick fix instead of manually
updating ?

Thank you in advance!!!
