Well I am curious about exactly which date it is sorting on when sorting by Oldest Date or Newest Date?
I’m assuming it is Capture Date or File Creation Date or File Modification Date. Is there another we can’t see?
Whichever date I have photos appearing in the ‘wrong’ order i.e. Where any of the above dates would suggest one photo should precede another… but it doesn’t. If this was just 1 or 2 photos it mightn’t be a problem… but it is a lot more than that!
Lightroom’s starting to look better and better :(
