The giveaway sign up page doesn't recognize my ISBN > Likes and Comments

This book is listed as a Kindle edition in GR, with the correct ASIN of B0F4Y6FS35. When I complete the ebook giveaway form and correctly copy this ASIN into the box and click Find, I get a message that the ASIN can't be found. If I search for this ASIN in the general search bar, my book is found in GR. I want to set up a giveaway -- can you help me? Thank you!
