Issues and Repository button not appearing

I am hoping to give my book the “link to repository”, “open issue”, and “suggest edits” functionality. Currently, my configuration looks like this

repository: 
  url: https://github.com/dafriedman97/mlbook


html:
  favicon: logo.png
  home_page_in_navbar: false
  use_edit_page_button: true
  use_issues_button: true
  use_repository_button: true

but on the book itself, I only see the button for “suggest edit”, rather than the buttons for “use repository” and “issues”. This can be seen from any page on the book. Any idea why I’m not seeing these other two buttons?

Thanks so much and please let me know if there is any additional information I can provide.

@dafriedman97 There is a warning in the docs to avoid mixing toc structures:

When designing the top-level sections of your _toc.yml file, you must pick either a list of chapters via - file: entries, or a list of parts via - part: entries with chapters inside of them. You cannot intermix them both.

Try commenting out the two - file: entries for table of contents and conventions_notation or adjust your structure to fit one of the two suggested formats.

Apologies, I hadn’t read the updated table of contents instructions.

To answer the original question, yes that worked! Thank you so much.

One new issue, though. The spacing between the “part” headers and “chapter” listings is looking funny (maybe something I’m doing?)

It looks like this right now. Note that “introduction”, “1. Ordinary Least Squares” and “2. Linear Regression Extensions” are the chapter titles, though that is misleading in this picture. Do you know how I can change that? And also, could I make them bigger or bold? Thanks!
