Headings in Stylesheet

[Venti]

I've read Flare's Table of Contents Guide but can't find a way to solve this problem.

I want to use h3 headings in my table of contents for a print, because the TOC only uses h1 and h2. I tried to add h3 as a heading style in the styles sheet but in vain.
According to the Guide, there should be six headings (h1-h6) listed in the heading style, but now the style sheet only left two headings (h1 - h2) for me.

How do I add h3 in the heading style?

Change the Show Heading Styles to Show All Styles and (this is optional, but I find it easier to use) change Show: Property Groups to Show: Alphabetical List. Then set the mc-heading-level property for h3 to 1.

Thank you. I've solved the issue.
