Lens profiles

I'm having lens correction profile issues.  I've read the problem/solution that others have posted, but can't seem to fix my lens profiles.  If I go into File/File info/Camera data, it lists the camera and lens I used for the picture, but when I go into Filter/lens correction/ and choos the make: Canon, model: 5D mark III, it populates the lens profiles with only two lenses, neither are close to what I was using.  At the same time, in the lower left corner of the same screen, the camera model, lens, and camera settings are all correctly displayed.  The image though looks like a fisheye because I haven't chosen something yet but when I chose one of the two lenses, the image is wrong too since they aren't close to what I shot the picture with.  How do I get the lenses I own into the library or wherever they need to be for access?
