Thanks for the reply. Sorry I should have mentioned - Don't import suspected duplicates IS checked. A workaround I just found is to cancel the import and just try again - the second time it seems to ignore previously imported photos.
- I believe it should do it in the first place as well, please make sure that LR is up to date.
- Also try importing same images from desktop, so that we can know if it is just the card of LR itself.(Lets see if it imports copies or not)
Thanks for the suggestions Rohit. Yes, I'm up-to-date - I'll try importing from desktop next time. I think it must be the SD card.
