Category, location, and event pages not formatted like WordPress posts and pages

I’ve followed the same rules for adding content to categories and locations that I have for content on a WordPress page or post, but it isn’t getting the same treatment, even though tinyMCE shows it as if it does. Is there a shortcode for specifying (e.g.) #_CATEGORYNOTES in a way that will cause the text to be passed through the WordPress text formatter?

Specifically, what I’m seeing is multiple lines of text being combined together. TinyMCE takes out any formatting I might add whenever I switch to the visual editor, so I’d like for these content shortcodes to be formatted like WordPress formats posts and pages.

Thanks,
David
