Prefab shows PhotonView attached but Unity not seeing it

Options
I purchased a 5 character asset from the store. I had all 5 prefabs working perfectly but now when I select one of the prefabs I get a "PhotonView not attached" error. The Inspector shows that it is attached. The prefab is configured exactly the same as the other four. I deleted this prefab and re-imported it. Re-configured it but same PhotonView error. Where is Unity storing information about this prefab? How can I fix it?
