I shot a timelapse and the numbers were in order, no problem. Shot another timelapse on the same card at a later date and the 2nd timelapse numbers were the same as the first timelapse numbers. The 1st timelapse numbers were re-numbered with a hypen 1. So now I have 2000 photos with the two timelapses mixed every other photo.
For example:
40001
40001-1
40002
40002-2
Why did this happen? What is an easy fix besides Ctrl+select every other photo and move to a new folder in Bridge?
