Auto numbering in appendices

[BenS]

Hi all,
I'm having a fight with auto numbering in appendices in Flare, and I think Flare's winning...
I have a book (printed output) with three heading levels. In the main contents, chapter numbers of all three levels work beautifully, but in the appendices level three doesn't update.
It looks something like this:
Appendix A Something cool
A.1. Subsection in A
A.1.1 Heading 3
A.1.1 Heading 3 stuck on 1 (no number increment)
etc...
A.2 Heading 2 works fine
A.2.1 Heading 3
A.2.1 Still stuck on 1
A.2.1 'Cmon already...
As mentioned before, the regular heading 3's in the document (before the appendices) work perfectly. The auto numbering in the h3 style is identical to the h3.Appendix. TOC settings are identical.
What am I missing here?

Can you copy/paste the definitions for the appendix styles from the CSS?

We actually use the same styles for h2 and h3 in an appendix. So what I have for print (taking out the formatting and just leaving the numbering):

h1
{
mc-auto-number-format: 'CH:Chapter {chapnum} ';
}

h1.Appendix
{
mc-auto-number-format: 'CH:Appendix {chapnum} ';
}

h2
{
mc-auto-number-format: 'CH:{chapnum}.{n+} ';
}

h3
{
mc-auto-number-format: 'CH:{chapnum}.{n}.{n+} ';
}

Then h2 and h3 are used for both regular chapters and appendices.
