The OP's bolt face almost looks like someone tried to rework the bolt head to change caliber. Factories can and do make mistakes, but that looks like a bad end mill job that got away. In any case, if I were still a gunsmith I certainly would not take it for repair except to return it to the factory. Note that if returned, send the whole rifle; due to headspacing concerns they will not, repeat not, take just the bolt.
