Left-out headers not shown as zero

[flaushi]

Assume I have a document like

1. Heading h1
2. Heading two h1
2.1 First H2
3. Third H1
3.0.1 First H3 (H2 is missing)

Then the output of the lib is

1. Heading h1
2. Heading two h1
2.1 First H2
3. Third H1
3.1 3.1.1 First H3 (H2 is missing)

Can I fix this just with an option?
My problem I guess is the "empty" li that is created and counts. It increments the leftout layer and gives the 1 instead of 0.

My corresponding css does behave as I'd like:

.toc ol {
			list-style-type: none;
			counter-reset: item;
			margin: 0;
			padding: 0;
		}


		.toc ol > li:before  {
            counter-increment: item;
            margin: 0;
            padding: 0;
			content: counters(item, ".") ". ";

		}

.report-content {
  counter-reset: h1counter;
}

.report-content  h1  {
    counter-increment: h1counter;
    counter-reset: h2counter h3counter h4counter;
}

.report-content h1:before {
    content: counters(h1counter, ".") " ";
    margin-right: 10px;
}

.report-content  h2 {
  counter-increment: h2counter;
  counter-reset: h3counter h4counter ;
}

.report-content  h2:before {
  content: counters(h1counter, ".") "." counters(h2counter, ".") " ";
  margin-right: 10px;
}

.report-content  h3 {
  counter-increment: h3counter;
  counter-reset: h4counter;
}

.report-content  h3:before {
    content: counters(h1counter, ".") "." counters(h2counter, ".") "." counters(h3counter, ".") " ";
    margin-right: 10px;
}
