Expansion Factions

Factions that are based on expansion content (KotN and SI) show up as blank when not a member instead of not being listed at all.
Steps to reproduce:
1. Create a character using the wizard.
2. Manage character.
3. Select 'Yes' for KotN and SI being installed.
4. Do not select any factions.
5. Click 'Modify All Sections'
This bug is hard to reproduce. I played around with it a lot to make it show up. Here are some characters who have this bug:
