I recently purchased the new Lightroom 6 but when I transfer the pictures from my camera to the computer, Lightroom doesn't detect the pictures in RAW only the JPG. My camera is a EOS80D.
Have you updated? Launch LR and go to the menu and click:
Help >> Updates
The latest version is LR6.8. The 80D needs al least LR6.5
You can see what version you are running by choosing About Lightroom
