Can't get sidebar on blog page only

Hi Sakin, I'm trying to get a sidebar on only my Blog page, not on any of the other pages. If I understand the instructions correctly, I should be able to set the default layout to 'no sidebar, full width,' then change the Blog page layout to 'right sidebar' in the page editor. However, this doesn't work for some reason - the sidebar doesn't appear on the Blog page. I can set 'right sidebar' as the default layout, and manually change every other page to 'no sidebar, full width.' That produces the desired result, except that the sidebar appears on WooCommerce product pages, and there seems to be no way to get rid of it. It's not on the side, either - it's in the lower right corner, under the product description tab (see here). Can you help me solve this problem? Thanks!
