Sorry if this has been asked before.

I am having an issue that I can only see episodes 1 - 38 of a program that has 50 plus episodes. They were all showing up while the program was airing each week. But now that it has finished I am restricted to just the first 38 episodes. The order has also changed to 1 to 38 whereas it always had the most recent episode first and went down to the first episode. I didn't record it because it has over two years viewing time listed

How can i view the rest of the episodes that I haven't watched.

Thanks
