This used to be a bug when High Isles was released, but for some reason it still seems to exist.
After killing the bosses, their corpses could be looted and even gave the double stickerbook items, but the daily quest did not register them as being killed. This does not always seem to be the case since the daily quest could be completed on a different character / account only recently.
