I'm trying to use the Superfish Nav instead of the custom nav that comes with the Typography theme. The alignment of the dropdown menus is coming out distorted and many of them are blank. It also pushes the entire content of the page down when the menus drop down.

I've tried disabling various custom CSS related to the header nav in various places but I can't seem to find the code I'm looking for.

Superfish works perfectly when placed in other locations on the page, it's just in HeaderNav that it freaks out, and I can't find the code that's doing it.
