Sidebar render issue

[erossini]

I'm creating a documentation about Agile. I have an interesting issue with the sidebar. For example, this is the Markdown I use for the Scrum section

* [Scrum](./scrum/intro.md)
  - [3 pillars](./scrum/pillars.md)
  - [Scrum team](./scrum/scrum-team.md)
    - [Product owner](./scrum/product-owner.md)
    - [Development team](./scrum/development-team.md)
    - [Scrum master](./scrum/scrum-master.md)
  - [Sprint events](./scrum/scrum-events.md)
    - [Sprint](./scrum/sprint.md)
    - [Sprint planning](./scrum/sprint-planning.md)
    - [Daily Scrum](./scrum/daily-scrum.md)
    - [Sprint Review](./scrum/sprint-review.md)
    - [Sprint retrospective](./scrum/sprint-retrospective.md)
  - [Artifacts](./scrum/artifacts.md)
    - [Product backlog](./scrum/product-backlog.md)
    - [Sprint backlog](./scrum/sprint-backlog.md)
    - [Increment](./scrum/increment.md)
  - [Advantages and disadvantages](./scrum/pros-cons.md)

the render for this sidebar is as the following image

I expect to see Scrum team with an arrow to see the details. Instead, I see immediately the submenu with a - like - Product owner under if I click on the arrow, there is no submenu for this option.

In the configuration, I added

      loadSidebar: true,
      maxLevel: 5,
      subMaxLevel: 5,

How can I fix this?

Thank you in advance, Enrico

If . /scrum/scrum-team.md exists h2, h3 ... etc. headings, it renders -
