Yeah, I admit I was stuck on what to name it too! Uncanny evokes a nature of mystery, which I'm not sure is totally approproate here.
Haha! I literally just Google'd "something that is attempted but misses the mark", after writing the above paragraph, and I found this article on Wikipedia [1]. It means "tragic flaw" or "to miss the mark". Feels quite apt! Perhaps "Hamartian Design" could work.
