Combine editions

[Terri]

Hello!
Can you please combine the editions of my book Simone Says together? It's the same book. The only thing that changed was the book cover. I'd like the cover with the words and the snow flakes to be the one readers see.

You should be able to combine editions yourself.
Only authors can set primary/default edition.

I'm sorry, Martin. I have no clue what I'm doing. That's why I asked for help. If I'm the only one that can set a book to primary, how do I do it?

Update:
I googled it, and found directions, but thank you so much for trying to help me!
