Show sublevels disabled

[HikariWS]

I’m trying to make a list style, I need each of its level to show sublevels, in exemple 1.1.1.1.1. for level 5.

I right click a paragraph with this style, enter Bullets and Numbering dialog and go to Options tab. Config is as follows:

Numbering: 1,2,3, …
Before: blank
After: )
Character Style: Numbering Symbols
Show sublevels: 1
Start at: 1

The problem is that Show sublevels is disabled, I can’t set anything other than 1 on it. What’s disabling it and how can I fix it?

Ok, if I uncheck Consecutive numbering I’m able to set sublevels, but then all list itens remain with number 1! How can I make numbers consecutive and still show sublevels?

If you have

1. Level1
2. Level2

That is expected. What you need to get

1. Level1
   1.1 Level2

is simply to add a Tab at the beginning of the second line. Add two tabs for level 3, etc
