Sync Issues with iCloud

So my Apple Books on my Mac, iPad, and iPhone will not sync completely. I have 2tb on iCloud with 1.45tb still available. Have a 1tb MacBook Pro and still have 659g left. I have created a new user I can get all my books to show up but it flickers and reduces by half the actual amount that I have on iCloud. Happens on my Admin account also. Not sure what to do. Any help would be helpful.

WOW, that’s a lot. I see a call to Support in your future :8ball:
