OneDrive Sync - Folder Gray Check - unavailable

[ESS-JW]

I have an older Laptop (Laptop Personal) running Windows 10 (cannot be upgraded). It syncs all folders and files with OneDrive without any issues. I have a new laptop (Laptop Biz) running Windows 11. On the new Laptop I am logged into my Microsoft account and have gone into OneDrive --> Settings --> Account --> Choose Folders and the primary folder I need to sync (Documents) is checked already but the check-box is gray (not blue). Within that folder, all the sub-folders also have gray check boxes next to them. I cannot select these gray boxes to change them to blue and thus designate them to sync. I need folders in that primary Documents folder to sync and be consistent across both laptops. Attached screenshot.
1. How do I designate the sub-folders in the gray-checked primary folders to be synched?
2. How can I designate some folders to sync with one laptop and some with the other?

THANKS!!!
