Sidebar Only Option?

Looking for a way to have the TOC appear in the sidebar widget only, and not in the page proper.

We set it to not auto insert on every page: https://www.screencast.com/t/LWODXPqUUd

We enabled it on the page we want it to appear: https://www.screencast.com/t/bJ6jQ1UX

We added the widget to the sidebar: https://www.screencast.com/t/ju22kjQwCb4

But it is showing up in both places: https://www.screencast.com/t/XcbJ3ISiIJ3Z

Thanks for any help.
