Sounds like you're...
 * 1) using an unsupported hack (Using *** instead of *).
 * This will allow you to bypass Wikia's control over what is shown and what's not supposed to be shown.
 * 1) Using a header that is longer than intended to fit within the space allotted.
 * Wikia suggests that you use shorter headings to alleviate this issue.

If you look at this post, you will see this was an intentional change by Wikia.
