I recently imported my outlook contact to my Outlook on my PC and now realize that many, but not all, of the contacts show up in my people name list in Photo Gallery. When that happened some of the names of people changed and I cannot get them back. For example, one name changed from Micha to Roberta and I cannot re-enter the name Micha - it just won't accept it. I needed to modify the name with a middle initial for it to take. It seems that some of the names that were replaced have been removed or hidden forever as if the "Don't Show Again" button was hit.

How can I remove ALL of the unwanted contacts from the "Tag As" people list ( the "cleanup unused tags" didn't work and I suspect that's why I cannot re-enter the "Micha" Name)? Plus how can I re-enter names that have been removed?
