The Rogue class doesn't load any features when the unchained version is chosen.
Also you can't seem to choose to not use combined skills and can't use Background skills.
I tried both in the previous nights nightly build
1) Class Skills not granted
2) Progression Variable wasn't on the main class ability
3) Rules enabled (COST=0, Correct TYPE)
4) Wound System set up to display
5) Class Progression stuff moved to abilities_class file
6) Consolidated skills that repeated a base skill removed
7) Background Skill selector set up
Testing those and then patch PR forthcoming.
