When you add movies to the Save List, often times multiple channels/apps will have the same content available.
If you try to play a movie from a channel/app that you do not have, Roku will automatically download and install it for you in order for the content to play.
If you saved a movie that it no longer available on a channel app (ie. Pluto) and only one other channel/app is carrying the content (ie. Hoopla), then Hoopla will download and open automatically.
Hoopla is a free channel/app (just need a library card and a participating library).
Are you sure you do not see Hoopla on your Home Screen? (new channels/apps are added to the end of the Home Screen).

If you want to prevent channels/apps from automatically installing themselves, you can login to your online dashboard at https://www.roku.com/ or https://my.roku.com/ and setup a PIN to help prevent this behavior. (it will at least alert you when it tries to install).
