Keep getting notification to update my appleid info on mac

Ever since installing Mojave... at least 4 times now, I will get a notification from System Preferences, saying that I need to update my Apple ID. When I click on iCloud settings at the top of the page it says "some account services won't be available until I sign in again. Each time it does this, Ive noticed that Photos & Keychain are not checked in the items listed that iCloud is going to backup. 4 different times now, I will add the checkmark to Keychain, it'll ask & I will put in my Apple ID password. Imediately it asks me for my Mac password. So I put it in & after a few seconds the notification will go away & the check mark will stay on for Keychain. All good. Each time, 2-3 days later I will get another notification starting the process all over again- Keychain not checked, photos not checked & the same error message. Can anyone shed some light? Thanks in advance!
