As I’ve mentioned above in my reply, these are all user hints. Created by other users. There is no many users who are learning Spanish with Spanish dictionary, that simple doesn’t make much sense. And that is why there’s only a few hints there, probably created by English speakers who thought they have English selected as dictionary language and saved English hints in Spanish instead.
The reason they weren’t fixed or moved to correct language so far, is simple because there are no users with Spanish dictionary set for learning Spanish.
