Hey folks! I've been updating my collections, and I want to replace some old tags with new ones. Unfortunately, once I've deleted the old tags, I can't add any new ones, because the page still says I have all 10 tags. When I delete all the old tags, then hit save, those tags are still there when the page reloads. When I add new tags to collections that had space for 'em, the tags don't save when the page is reloaded.

Help!
