I’ve noticed something strange. I have entered descriptions for my post categories from the backend. Whenever I create a header element to be displayed in a certain post category archive and set the title tag on the header like this <h1>{{post_title}}</h1>, the category description is not displayed on the category archive. If I hardcode a text entry, though, like this, <h1>Events</h1>, I get the category description at the top of the category archive!
