I'm not sure, but you are probably using iPhoto now. And if you change names, make albums, etc. those changes exist in iPhoto only. Some applications can access that iPhoto info, but that's where it is. And you need to distinguish between the photo name/title, and the file name; they aren't necessarily the same.
Lightroom can import existing iPhoto albums, and probably the names you are referring to. Not sure whether there are others.
