The Nether Furnace is listed twice with the second one missing its texture in the JEI item list.

The-Fireplace fixed the issue, maybe he can help.

The Furnace without texture is the lit one which can't be crafted. I worked around the issue by putting it on the JEI blacklist.

Thanks for the list, hadn't seen a good way to do that yet with JEI :)
