Please separate https://www.goodreads.com/book/show/2... from being listed under "Best Laid Plans."

I have created a new entry for ASIN B0DF6C7BLZ but I can't make that the "main entry" as the ASIN B0DF6C7BLZ is attached to the wrong book. Thank you for your help.

P.s. I have tried to use the separate tool but I get an error. My apologies for bothering you.

I did separate the book but have been unable to combine with the other edition, I will try again later.
What is the problem, does the edition with correct ASIN show an unused placeholder cover?

I have now combined the two editions.
Please explain ASIN difficulty in more detail.
