Troubles saving custom difficulties under anything but 1

[Atomic Pasta]

As the title states. The game won't let me save my custom difficulties on anything but custom 1. There's no guides that explain exactly what you need to do for this, implying it's insanely easy to do so I don't know if it's user error or if the game is just broken for me.
