Can't get css properties right on javascript menu items

Please take a look at this web page: http://www.discretedata.com/JCRD/Tiffany/tiffany_beta1.html

I'm trying to re-format an existing js menu I've used elsewhere, and I can't seem to get it right.

1) If you look at the image below you can see that "Brides 1" has a dark purple background while the other two instances of the same element don't.
2) I want the default dropdown ("Brides 1")  to have the same width as its parent (in this case "GALLERY", and to be left aligned with it. Same goes for the hover state ("Brides 3")

I'm embarrassed to say I've been trying to get this right for almost 2 hours, and can't figure it out.

It might be something in the javascript file, but it's packed. If you know of a utility that will unpack it, please let me know.

Thanks,
John
