I have File Name Order selected 98% of the time, and as the name of the new file created by the external editor is identical apart from a suffix, this should NOT change the order - the new file should simply appear alongside its progenitor. But no - LR changes the strip view to Custom Order - every single time! - and both the original and the new file appear together at the end of the strip. There is no reason for it to change to Custom Order.

Annoying, yes! The same happens when you view as Descending or Ascending Order, (which I always do) because the file you just created has the newest date, so it goes at the end (either top or bottom, depending). What I do is stack it with the original, then it goes back where it belongs (but you may have to change Sort Order from "Custom" back to Descending).

When I go into an external editor, and then come back into Lightroom Classic, it has changed the order of the filmstrip from whatever I previously had to "Custom Order"! I most definitely did not give it permission to do this, and it is intensely irritating if you are working through a series of images in a folder sequentially, and editing quite a few; I have to keep changing back to the original order typically Filename)
