Version 18.1.3.65 (UDP3) The photos were originally taken by a canon 80D and post edited using lightroom CC. The show was created under all automatic and default settings. The export preset was 1080P. Thank you for helping... Sorry for not putting this information earlier.

I suspect Lightroom is non-destructively embedding the edit changes within the DNG file which Photostory is picking up correctly, however it ignores the embedded edits when exporting.
Exporting from Lightroom as JPG files and using these in Photostory should fix the issue.
