TV Season says purchased but individual episodes still need to be bought

A few years ago, I purchased a whole season of Survivor. I watched it, and it sat in my iTunes library for the longest time. Sometime last year, I was clearing out my computer for a software update because I did not have enough storage and I cleared the season out of my library to make space. Yesterday I go to re-download the season to my library and it says that the season is purchased, but all of the individual episodes need to be bought. An image is attached for reference. I was wondering if this is just a glitch, or do I need to purchase each episode again?
