How to fix: Writer is showing paragraphs in index table?

[hanktomoffice]

Using the latest LibreOffice writer on Ubuntu I ran into some strange issue:

For some reason paragraphs are appearing in my index table, while the only entries in here should obviously be the Headings. I checked the paragraphs style and it did not have any Heading styles applied to it. What could be the issue and how do I solve it?

Thanks!

Hi

Right click paragraph (in the document), then Paragraph, Outline & Numbering tab, Ouline level: Body text.
