I am questioning why there are 267 photos listed at the lower left of the Import screen grid:
But the second screenshot with the error message only lists 133 as having errors:
Are your screenshots from two separate imports or why is one count twice+1 the other?
I mean your options are New Photos not All Photos so it would seem like there should only be 133 New Photos on the first screenshot. Maybe it wasn't finished looking for duplicates when you made the screenshot?
