when I export pictures to an external editor, Lightroom moves the picture and the copy of it to the far end of the stack. This is a new phenomenon, usually the picture stays at its place and the copy is simply attached to it (chronological order). I use Lightroom 5.7, external editors are PSE 14 and Affinity Photo. Problem occurs with both editors alike. No recent updates, no changes in settings. Can you help me?

Change the sort order to by Capture Time.
Use the menu command View->Sort
This actually did the trick. So embarrassing, that I didn´t think of it myself.
Thank you so much for your help!
