there is a problem I'm not able to solve by myself.
I have imported some pictures from my camera to my iPad in Lr on the go. The pictured synced with the cloud and back at home with LrC on my PC => so I got the RAW files now in LrC.
After that I wanted to import the rest of the pictures from my camera in LrC but LrC didn't recongnised that there are already some of the pictures already on my PC. I even chosed the same folder where the pictures already are and they still have the same file name. When I import them anyway, LrC renamed the new duplicated picture with a - 2 file ending.
