Upfront Header/Footer not saving

Using Spirit 0.1.4 and Upfront 0.2.3, when I make changes to the header/footer areas, and save, it does not save them at all. Immediately after saving if I try to navigate to another page it warns me that there are unsaved changes, and then when I navigate away I see that my changes are indeed not there.

I have tried:
Logging in as the individual site's admin
Logging in as the network admin
Creating fresh test sites
Using the save button on the left panel
Using the right click save menu
Saving using the Home Page
Saving using sub pages
etc. etc. etc.
