Deep numbering showing in content with toc="no" attribute

[Birgitte]

Hi!

I am facing an issue with deep numbering where topics with the attribute toc="no" are numbered in the content. Is there a way to get around this?

Example:
The topic related_documentation.dita has the attribute toc set to no.
It doesn't show in the TOC in the output, but the numbering shows in the content in the output.
