Are you able to Edit an Announcement to Delay Posting?

I've got a bunch of announcements in a course I imported that were delayed in their original course.   Now that I've imported them into the new course, the Delay date is unset.   I go Edit the Announcement, check the box to Delay Posting, and enter a valid date a few days in the future.  When I click Save, the spinner appears briefly, but then nothing happens.  I remain on the Edit page.  The post isn't saved, and the Delayed Posting isn't enabled.   The post remains active. 

Is this a bug, or am I missing something related to Delaying the posting of an active anouncement?
