If this is a newer Panasonic camera, a micro 4/3 (MFT) camera, then it is likely that the lens profiles are built in and always on, invisibly doing their job, therefore cannot be selected or deselected in a list of profiles.
Starting with, I think, ACR 8.4 for Photoshop, there is information about whether a built-in profile is being used or not, but LR, as yet, doesn't have this indication so questions like yours arise all the time.
If you want to post an example files, using dropbox then someone with PS may be able to tell you if your camera has built-in profiles or not.
