XFinity Stream app issues on Roku

We have two devices that use Roku. The Xfinity Stream app is installed on both. I purchased all seasons of a Disney show several years ago. A few days ago, we are only allowed to view the last season using the Xfinity app on Roku. The first season does not display at all. Using the app on my LG tv works fine. it's just Roku. I confirmed I am using the latest version of the app.
