I have 9 categories.

I added two new categories and renamed a two others. The ones that I renamed are fine, as are all the ones that I left alone, but the two new ones do not show in the Categories with Products that are Available for Linking ... section, and I need to link to one of the categories that is not available for linking. I am sure it is a simple fix, but I cannot figure it out. The fact that it is 4:00am does not help.
