I've assigned a category to a blog post. But when I go into the blog page, under categories, it shows the post assigned to a category. When I go to Manage Blog posts and choose my post and go to Categories, it shows that I have assigned the correct category to the post. I've done the same with another blog post in a different category and it shows up on the Home page and the page (category) it was assigned to. But this other one only shows on the Home page and not the page (category) is was assigned to.
