The sidebar shouldn't appear on the main page, because unlike other pages, in the main page you have contents on this area too.

As for template pages - could you link an example please? This is way more helpful than a screenshot.

You cannot directly edit the right rail, and you are not allowed to change it with custom CSS, but some dev wiki scripts affect it - for example the DiscordIntegrator you already have.
