Can you read the books? Do they show in your purchase history?

Did you buy them on mobile? That sometimes takes on the order of a day to sync up.

Are your entitlements synced?

What options do you have turned on in the character builder? PHB is 5.5 core, and the ravenloft book will be either 5.5 extended or 5.0 extended, depending on which book.

Are you sure you're using the 5.5 paladin class?
