Outline levels are different to multi-level lists

Outline levels (as seen in the Outline view) are configurable in the Format Paragraph dialog and are typically associated with Headings 1 through 9. Those headings can also have multilevel lists applied to them if numbering is required but this is independent of the outline level. You can also assign the outline levels to other styles if you wish.

Multi-level lists can have 9 levels of indentation but you will need to associate styles with each level if you want to have those styles show up in the outline view.

The simplest fix is to apply headings to the paragraphs you want to see in outline.
