Forum:Lucifer Edits Needed

I recently fused Lucifer in Devil Survivor 2: Record Breaker, and by recently, I mean about two days ago. The website said he Resisted everything but Curse, which he Nulls - reading this, I was almost too happy to fuse him, considering that I had impressions he was the Invincible Demon of the game, with the only attack type able to hit him being Almighty. So I put together Metatron and Loki, and I set up the fusion to go through. Once Lucifer appeared, I went to check him out, but it only said that he was Strong against everything. Curse remained Null, but from Phys to Force, it was Str, not Resist

Is this a glitch in my game, or is this what JohneAwesome (<Youtuber I'm watching for a Triumphant Ending Guide) referred to as a Fusion Failure, because I don't want to outright call the website incorrect.
