CORRECTION REGARDING THE PAPERBACK COVER

Issues with paperback size

HOW DO I ADDRESS AMAZON'S CORRECTION REGARDING THE PAPERBACK COVER?

Hello everyone,
Peace be upon you, all.
It's great to be able to share news in this community.
Over the past two weeks, I've been busy promoting my novel, Sakura Bloom at Dusk: A Cross-Cultural Love Story Between Japan and Indonesia, on my social media.
Through this article, I want to share the issues I've encountered.
By the way, I want you all to know that Sakura Bloom at Dusk is now available in ebook and hardcover formats on the Amazon Kindle Store. I don't know why, but the paperback cover of Sakura Bloom at Dusk keeps getting rejected because I need to add a 0.125" bleed on each side.
I've followed all the instructions I received from Amazon regarding the cover size of my paperback book, but Amazon's system keeps correcting it.
I've counted seven emails I've received about the paperback size correction.
Are there any community members experiencing the same issue?
For your information, Sakura Bloom at Dusk is printed at 9" x 6" and has 334 pages, equivalent to a 0.835" spin thickness. Therefore, the paperback canvas calculation is as follows:
Cover height = 9" + (2 x 0.125" for bleed) = 9.250"
Cover width = 6" front cover + 0.835" spin + 6" back cover + (2 x 0.125" for bleed) = 13.085"
What do you think, fellow writers? Can anyone offer any advice?
Thank you.
Rama Lebe,
Author of Sakura Bloom at Dusk.
