apple tv not displaying purchased episodes

I have purchased the entire season of the kids show Bluey. Only 8 episodes are available though and it requests me to pay again in order to unlock the balance of the episodes. There are 52 episodes in season 1. I have called the Apple support roughly 6 times and the issue persists. No one helps or comes back to me. Seems such a simple fix but apple either unwilling or unable to assist. About to give up as it is a 50 minute phonecall each time with the same advice and discussion points but absolutely pointless in the end.
