You need to set it to Full Gen in the Pregen UI.
As for Command pregeneration, i believe it should be full gen by default, if it's not, there should be a way to make it, check their curseforge page.
Also, for issues like this, please come to our Discord, it's linked on our Curseforge page, and also a message when you log into a world in the pack.
