Check to ensure that you are working on a raw file, and not a jpeg file. Lens Profiles are primarily created for raw images only, and so they will not show up in the list when processing a non-raw file. There is a very much smaller set of lens profiles which can be used on jpeg files, so you get a much smaller list.
Similarly, all the camera profiles are applicable for raw files only, so are not shown when a non-raw image is selected.
It certainly seems that you probably have a non-raw file selected.
