Thanks for the quick response!
It turns out that two of my galleries had hide owner checked. Unchecking it fixed the problem. However, this gallery (http://www.smugmug.com/gallery/7421190_eGFLM#478298921_FCPKs) had both of your recommended settings correctly configured but it still won't display my custom settings.
No it doesn't, just need to fix the link in your nav.
<li><a href="http://www.smugmug.com/gallery/7421190_eGFLM#478298921_FCPKs" title="My Favorites">Favorites</a></li>
The www.smugmug.com will also disable your customization.
Here's your whole header with some corrections and link changes to relative
<div id="my_header">
