That's normal. It means you blocked the IP of that guy, and the "autoblock" is actually the IP block of that guy except that you can't see their IP (Yeah, Wikia tends to hide users' IPs unless you have checkuser).

That means, if the user logs in through their account, they will be displayed the first block reason, and if they don't log in or log in with a different account, they will be displayed the "autoblock" reason. Of course, until the autoblock expires.
