Org-Mode Headings show up as ordered lists?

I'm having trouble moving from markdown to org-mode (my favorite markup). In markdown # converts to an h1, ## converts to h2, ### converts to h3 and so on. In org-mode * converts to h1, ** converts to h2, however *** converts to an ordered list.

I would prefer for there to be parity between markdown and org-mode so that all heading levels regardless of format would convert to their respective HTML heading tags.
