Replacing Placeholder Cover/Removing Incorrect Edition > Likes and Comments

I was trying to update the placeholder cover on my book to the final artwork, and tried making a separate edition and then combining them. However, I am unsure that I did it correctly. The ASIN's do not match, and I cannot get them to combine. I also could not just update the artwork on my original book listing.

I am new to this so I apologize for the errors. If someone could help me get this corrected, or tell me how to correct it, I would really appreciate it.

Thanks.

Creating a new book record is not the way to edit an existing book record...

I have removed the placeholder image. You can now simply upload the real cover.
