Sims 4 expansion pack needing repurchase?

Hello, I am hoping someone can help me out. I have contacted support and I have not been given a solution. The agent I spoke with said that it is no possible that I was playing the island living expansion pack with my sims 4 game. I have had my game for years now and all the sudden I can't not play the expansion pack after an update. It is telling me I need to repurchase in order to play the expansion pack. It is not anywhere on my Xbox. I have only one profile for the Xbox so I know that it is on the right account. I've attached photos. I have been playing it on Xbox one. Thank you!
