RH2022 PDF output TOC numbering does not equal topic heading numbering

(RoboHelp 2022.0.346)

Hello

I use following code to number the headings and this works perfect.

@media print
body {counter-reset: h1cntr 0}
  h1 {counter-reset: h2cntr}
  h2 {counter-reset: h3cntr}
  h3 {counter-reset: h4cntr}
  h4 {counter-reset: h5cntr}

  h1:before {counter-increment: h1cntr; content: counter(h1cntr) ". "}
  h2:before {counter-increment: h2cntr; content: counter(h1cntr) "." counter(h2cntr) " "}
  h3:before {counter-increment: h3cntr; content: counter(h1cntr) "." counter(h2cntr) "." counter(h3cntr) " "}
  h4:before {counter-increment: h4cntr; content: counter(h1cntr) "." counter(h2cntr) "." counter(h3cntr) "." counter(h4cntr) " "}
  h5:before {counter-increment: h5cntr; content: counter(h1cntr) "." counter(h2cntr) "." counter(h3cntr) "." counter(h4cntr) "." counter(h5cntr) " "}

The result is for example:

1. Topic 1, Heading 1

2. Topic 2, Heading 1

2.1 Topic 2, Heading 2

2.2 Topic 2, Heading 2

3. Section, Title

3.1 Topic 2, Heading 1

3.1.1 Topic 2, Heading 2

3.1.2 Topic 2, Heading 2

3.2 Topic 3, Heading 1

3.2.1 Topic 2, Heading 2

3.2.2 Topic 2, Heading 2

The TOC however shows the following (I underlined and bolded the errors):

1. Topic 1, Heading 1

2. Topic 2, Heading 1

2.1 Topic 2, Heading 2

2.1 Topic 2, Heading 2

3. Section, Title

3.1 Topic 2, Heading 1

3.1.1 Topic 2, Heading 2

3.1.1 Topic 2, Heading 2

3.1 Topic 3, Heading 1

3.2.1 Topic 2, Heading 2

3.2.1 Topic 2, Heading 2

Can this be solved via CSS code?

Or is it a bug?

Thanks in advance
