Horizontal spacing difference mystery between two scores

I have two versions of the same song, original and easier. Easier has compressed horizontal spacing that I would like to use in Original, but I can't remember or figure out how I reduced the spacing in Easier. I tried saving the style from Easier and loading to Original, but it didn't make much difference. I have hunted everywhere. But I can't figure out what is the difference in the spacing between these two scores. Can you help?
