YAML configuration not working for some of the options when using nixpkgs version (1.2)

[madsamjp]

Describe the bug
When trying to configure emanote with the index.yaml file, some of the options do not work (whereas others do indicating I'm not doing it wrong)

To Reproduce
Create YAML in root directory called index.yaml:

template:
  theme: red
  sidebar:
    enable: false
  toc:
    enable: true

Then create index.md

# Testing YAML config

## a heading
dfiadf adfadf

## another
adfadsfasdf

This is the page that I get:

I've also noticed this for other options such as uptree: enable: true

As a related side issue, I've also noticed issues with syntax highlighting of code snippets. When configured correctly, sometimes it renders and sometimes it doesnt.

Expected behavior
I expect to see a TOC, and for the sidebar to not be present. As you can see, the theme is red, so some of the options are working.

Desktop (please complete the following information):

• Browser firefox
• Version 1.2

Don't use the one from nixpkgs.
