Hello! I see two cards that you uploaded yesterday in your gallery. There was a third card that was deleted? Can you add a 0 or something to the end of your file name and reupload? That should do it.
The reason items are removed in our scan for duplicates is this: our computers look at filenames, and will compare. If there's a file name that's the same as another already in *your* gallery, it'll remove the most recent version.
