Camera Upload album? Also, duplicate remover needed

Just beginning to try to use Plex for photos. Camera Upload is working (from iOS to Mac server), but it’s not behaving like I expected. On my iPhone, I selected those uploaded photos to be in a new album. But when I go albums, all I see is favorites. But if I go to grid/photo view, there’s the iPhone album, oldest on top, but it’s there. And there’s a folder with the iPhone photos as well.

Is that working as expected? Cuz I would expect album to mean album, not folder.

Also, if anyone has any photo duplicate remover (Mac) recommendations I’d gladly take them. Or any times for exporting from Photos & iPhone. I don’t use Apple’s iCloud Photo Library, but I do use Photo Stream. So when I exported my Photos library, and then turned on Camera Upload, there’s probably 1700 duplicates, though they have different file names.
