Let me reword this, in hopes of an answer.
On IMPORT, a previous file shows up. I don't want that file and it was never imported. CANCEL gets me out of IMPORT, but when I go back, the file is still there.
Thanks for any ideas.
The import dialog box will always show you every photo in the folder that you select to import, or by selecting the right option, only the new (not previously imported) photos in that folder. There is no way to stop this from happening in LR. (You can prevent it from happening by going into your operating system and move that unwanted photo to somewhere else)
You can choose the photos that you want to import by placing a check mark on them and then clicking on Import
