I just completed mission 7 in campain mode with an  rank. It came up on screen that I had earned a new nickname..."demon destroyer" but it is not in my nickname list. Is this a common problem?

I have tried to get the nickname again. repeatedly finishing it with an s rank and 34,500 pints but still no nickname. Anybody have any ideas?
