Gnome not appearing at anvil at mount steep

@DeathSeeksUs I went ahead and made a new account, gathered only that gnome, and went to the shrine.  My findings were that the gnome from the anvil corresponds to the bottom row, second from the right and is not the one in the far right that you mentioned.  Attached is an image for reference.

Unfortunately I cannot help you determine the exact gnome you are missing but it does not seem the anvil is bugged at the moment.
