New Sprites Can't Be Equipped On The Pod?

The new sprites that were recently released, such as Batman, Air, Seven, & Pollo don't even show up as options with the Sprite Pod back-bling, whereas variants that aren't even in the game yet do? Will this be fixed in a future update or did I waste my time mastering them?

I figure it will be, but better off being sure rather than wasting hours of my time.
