Can't get the sidebar to show on a page

Hi.

I’m having trouble getting the sidebar to show on a page I created.

Bellow is the page. I want the sidebar to show to the right.

On the page settings, I have “default sidebar” selected, but it has no effect on this page.

If I try to edit the page with TD Composer, the image bellow is what it Shows. I can’t add stuff to the right, only on top. Also, if I try to add the “sidebar widget”, it doesnt work. It only get’s added to that space that says “Empty Column”, but after that, I can’t add anything inside of it.

Any tips?
