the Racial Heritage feat from APG only allows Dwarf, Elf, Gnome, Halfling, and Orc.
It should allow selection of any race with the Humanoid subtype (Such as Catfolk, Drow, Goblin, etc...)
This technically isn't a bug so much as a maintenance issue. We would need to add the support for this feat for each new playable race that came along. There are a few other instances of this need for minor rules to be kept up-to-date with all new sources. I can look into setting up something to make such additions easier, but it may take some time.
