I have this strange thing that started happening a few days ago
When importing to LR, (CC2015.3 windows 10 64 bit) directly from a SD card inserted into a built in card slot, the application doesn't remember the photos that I already imported. I have 200 photos, import a certain number of them, let's say 40. I make sure I have clicked "new photos" but ALL photos show up. At first I thought the camera was duplicating shots when it wrote, but this is not the issue. I have shut down LR and rebooted computer. This happens on 2 different cards, from 2 different cameras.
Thanks so much
