You’re messing up everything!
Heading n are already preset for chapter numbering, except that numbering is not enabled (because some document may use unnumbered headings).
The “counter” for headings is Tools
>Chapter Numbering
. When you right-click on a heading and change the counter for Numbering 123, you change it only for this heading (direct formatting). You end up with two numbering sequences. I assume you did that on “Spending” or “Retirement” and the result is consistent.
Rule #1: don’t fiddle with the numbering style unless you know what you’re doing; Chapter Numbering
is dedicated to headings.
Though not directly related to your problem, when you customise list styles (those controlling numbering, accessed from the fifth little icon in the style side-pane toolbar), don’t use the Bullets
, Numbering Style
, Outline
and Graphics
tabs once you have begun to customise the style. They change values in the Position
and Options
tabs and ruin your customisation.
Rule #2: use only the Position
and Options
tabs in list styles.
To enable numbering, open Tools
>Chapter Numbering
, Numbering
tab. To configure simultaneously all levels, select 1-10. Menu Number controls the style of numbering. By default, None
tells to not number. Choose 1, 2, 3
for a numeric numbering.
Rule #3: heading numbering is controlled from Tools
>Chapter Numbering
.
When you right-click in text to change anything, you only apply a local change (called direct formatting) without modifying the underlying style(s) (paragraph, character, list or even page). Therefore, if you modify again, you’ll still see the styles as they are configured, without the local changes because they live in a different layer.
Rule #4: to get persistent changes, modify styles in the styles side-pane, not in the text.
And finally:
Golden rule: download and read the free user guide from the official site, notably the chapter about styles.
