Anna and Elsa are not official members of the Disney Princess franchise, holding lesser positions along with Megara (Hercules), Giselle (Enchanted), and even Minnie Mouse (don't ask). Thus they may appear with other princesses, but are not card-carrying members of the franchise.

Why is this?

It seems that the powers-that-be at Disney decided that Frozen was too profitable as its own franchise and in order to not have duplication of effort (for example, Elsa branded as both Disney Princesses[tm] and Frozen[tm] with distinct packaging for each), they decided to keep them separate, much like the way they removed Tinkerbell from the Princesses franchise when they created the Disney Fairies franchise.
