Help with race selector

[Henry_AC]

I just created a custom race and to choose it you must select the Humans, now the problem is that I am creating one but of the Undead, but the detonators to choose the custom race do not work, it guided me from the detonators that I use with humans, but it doesn't work, the detonator is supposed to replace the necropolis, the acolyte, but with the mine and the necrophage I don't know what to do.
