The Simpsons season

Ok, I have all the seasons from The Simpsons through iTunes. I get an email[ that the newest episodes of both Simpsons and Bob's Burgers are available. Yet, the episodes will not show up in the store. So, I cannot download them. Oddly enough, I just got something on my iPhone that said it was ready, I clicked it and could watch on my phone. Anyone have any idea why this is happening.
