I have created Head 2 New inherited from Heading 2.
If I use it I have this:
as you can see, Fourth, that is head 2 new style, has no numbering.
The numbering settings in styles is:
On the left there is the setting for Heading 2 and on the right there is head 2 new one.
I need that head 2 new had the same numbering of Heading 2. In the example Fourth should be numbered 1.3
