another "does not meet our catalog guidelines" book

[Daisy]

This book has the "does not meet our catalog guidelines" warning at the top, and as far as I can tell, it's not for any of the reasons provided. I found the advice somebody gave downthread to go to the Edit page, do nothing, and save, but that didn't work here - I tried doing nothing and then I tried changing the status from Invalid to Public, but I'm still getting that warning at the top of the book's page. I'd appreciate any guidance. Thanks.

It takes some time for the warning to disappear from the book page. Seems to be okay now.
