Codex entry for Terror Demon bugged

Despite having killed several of these guys the codex entry for them will not unlock as it should. It isn't until I turn in several of their related research items that the codex entry finally appears. Unfortunately the entry is pretty much blank as can be seen with the following link : http://i59.tinypic.com/2460ykh.jpg

I know it was stated in patch notes:

"Fixed an issue which caused a couple creature research codex entries to not increment correctly."

But it looks like this one is still a problem.
