I'm not sure how this happened, but all the photos that I rated as '5 star' suddenly are all ordered sequentially one after another. They usually remain scattered amongst my other photos that have '4 star' ratings, which is what I want. Why did the '5 star' rated photos suddenly line up sequentially with all the unrated and other rated photos following thereafter? I tried all the filters that are already there to see what could have happened, but nothing. Help!
Look for a sort popup button at the bottom of your window. It is probably set to "rating". Change it to Capture time or whatever sort you prefer.
