Reschedule Glitch

I've never had a problem rescheduling before, but today when I tried to push my program one day ahead, there's a glitch. It lets me see the preview of the scheduled change, which is correct, but then when I click on Confirm, it boots me back to the Reschedule page with the attached error message, i.e. claims I left the "start at" and "move to" fields blank, which I didn't. Is this happening to anyone else?
