Can't turn off Sidebar on Woocommerce

In WooCommerce when creating a product it shows:

Default
Content / Sidebar
Sidebar / Content
Content (no sidebars)
Sidebar / Content / Sidebar
Sidebar / Sidebar / Content
Content / Sidebar / Sidebar

I clicked Content (no sidebars), but the left sidebar still shows on the page.

At first I wanted sidebar but I changed my mind. I cleared the browsers cache and even tried other browsers, but it won't go away.

Does my problem pertain to the theme or to the woocommerce plugin? Thank you.
