I can see how the TD Panel allows the Blog category design to be set on that tab. But when I open all my old posts, the same design isnt selected at the bottom of each post. If I happen to edit a page, it changes to that alternate design.
Example - the Blog tab has 1 column, background type medium. I open any blog post and it says "dark" and "sidebar left" but the post displays with a white background and full width. It doesnt match anything.
How do I change this? I do not want to update over 80 blog posts by hand!
