Steps to reproduce (I think...):
1. Select a spell, click on it to go to the Hiergamenon.
2. exit the Hiergamenon back to the main game map
3. go to the Hiergamenon directly, see that you're pretty much stuck on the spell category. (You can change which spell to look at, but can't get out of that category.
Note that this was based upon just a couple hours of playing yesterday night, I'm not actually positive these are the right steps...
