It appears to be fixed on my end!
Haven't tried streaming from the xbox yet but both show as UHD so that's good.
some strangeness still going on as its showing I own 2 copies of Avengers (one UHD and one HD) and 2 copies of Avengers: Age of Ultron (both in UHD), although the old cover art one simply points to the correct cover art one. I will summarize and attach
a graphic to illustrate.

The Avengers: Age of Ultron - Bonus Content 2015Has the wrong cover art but when clicked opens to Avengers: Age of Ultron in UHD with the correct cover art. (perhaps linked??)
