sidebar position

I am new using shapely theme on wordpress. I have troubles with the sidebar.
First problem is that the sidebar do not appear when i chose the default template.
Second problem is that if i select the right-sidebar or the left-sidebar, it appears under my paragraph, and not left or right of the page.
How can I make the sidebar appear on the right of the page?

Thank you for your help!
