This was a great question of the book being in KDP Expanded Distribution. The author wants to take it wide with IngramSpark. But they also have a second edition ready to release.
In this case, I would suggest:
1. Go through the process of creating and linking the second edition with Amazon KDP. Don't select expanded distribution on the second edition!
2. Once the book is live then upload it to IngramSpark. Use the expanded detail to note it is a second edition.
