No Rogue Dedication?
 

I am looking at the list of Dedications under Class Feats on my Barbarian, and I do not see a Rogue Dedication in the list?

Rogue Dedication is not under 2nd level Feats. It is under 2nd level Archetype Feats, which is just below 2nd level Feats, and is by default collapsed (I assume it's collapsed since there are a lot of them).

Indeed, listing the dedication feats separately (especially the 2nd level ones) is a change we made with the release of the Advanced Player's Guide. There were so many new archetypes added in the APG that we were concerned about users looking for their class feats having trouble finding them among all the dedication feats.
