Can't change background in character creation

[Filthy Degenerate]

It's stuck on Haunted one, it won't let me change it when i click it.

[Clovis Sangrail]

That's because you are trying to use Dark Urge, which only has that option. Origin characters only have a designated background.

[LordAnubis]

Dark Urge allows you to pick your race and class options, but he is stuck with that background.
