Are you looking at a JPG or TIF or PSD rather than a raw file?
Lens profiles are specific to raws or non-raws with almost all lens profiles being for only raws. The reason for the separation is that cameras can correct for lens distortion or vignetting before writing out the JPGs and likewise Photoshop has lens corrections possible, so if the camera or software is doing the corrections and then LR also does the corrections, the result would be double-corrections, with a light vignette and reverse distortion of what the lens produced.
I am shooting RAW only
Can you upload one of your raw files to dropbox and post a share link to a message, here?
