How long have you waited for the percentages to load?See the screen shot. The right column should show percentages. It doesn't. I've tried force rebooting the iPad. Any other ideas?

Have you tried doing a force-close of the settings? While I haven't had problems with settings, I have had other apps freeze up or act goofy until forcing them closed and restarting. On the few times that an alphas acted goofy it is when I haven't shut down or restarted my iPad in a while.
I did try force quitting the Settings app. No joy.
