I customised the headings to make the relationship between them clearer (some of the defaults were hard to tell which was a heading which was a subheading).
I now want the headings to be numbered in the relationship:
1. Heading
1.1 Subheading
1.1.1 Subsubheading
When I follow the instructions here:

it affects only the first heading and none of those below it:
Does anyone know how to fix this? Thanks.
