Generic Shooter: Support Thread

I am looking at the Generic Shooter - Adding A Custom Character , however when I select the skel_common all bones are missing except for the head. Is there a way to change this ? I have tried to activate another project and this still does the same thing. I am using the Mixamo toons pack however that should not make a difference should it?

EDIT: Found out from that you have to rename the bones in the Mixamo. Don’t know what i was thinking, because they are not on the Unreal Skeleton I should have known that
