Bursts where you can't "Keep Only Selection"
Have noticed this a few times in a few different Photos libraries.
When sifting through burst photos, sometimes when you make your selection and click 'Done', it asks "would you like to keep" question and gives you the option to "Keep Only Selection" or "Keep Everything" (which I would call normal behavior). But sometimes it never asks the question and just "keeps everything". There no way to get rid of the ones you don't want.
Any explanation why on some bursts you can't "Keep Only Selection"?
