shared photos not picking up metadata changes

After upgrading to Aperture 3.3, I've noticed that if I update the metadata on a master of a previously shared image, the changes are never pushed to the shared image.

I'm trying to update a few keywords and image titles on some flickr photos I uploaded last week, and it refuses to push any changes to flickr.

Anyone else running into a similar situation after updated to 3.3? Any workarounds?
