Have you updated your breed addon?
Not all addons have accounted for the recent 20%ish nerf in power to all wild pets out in the world, and may thusly confuse some addons if not updated. Battle Pet BreedId have updated to recognize the proper breeds even with the power nerf.
Rest assured that wild pets once caught, will have their proper power values.
I hope you did not release the rares you found.
