Apple TV Siri search showing some movie content as if not purchased

In the last few days I've noticed that Siri searches (Apple TV 4th gen) are returning some of my movie content as if I have not previously purchased it. For example, I've purchased both Captain America movies, but when I do a Siri search for "Captain America", the first Captain America movie shows options to purchase it while the second one shows that I can play it. In both cases, I can browse Purchased movies and see (and play) them both. (Both are HD versions as well.)

Seeing some of the same behavior with some other movies as well: present in my Purchased library but Siri shows them as needing to be purchased.
