Just checked - in Germany, the movie appears with a really huge "KAUFEN ODER AUSLEIHEN" (that's "BUY OR RENT") button on the top of the list, then again with a smaller button in different color with (again) "KAUFEN ODER AUSLEIHEN" further down the list. Plus a couple of other buy/rental movies.
Probably a matter of advertising standards (EU/German versus UK standards?).
So for me, this is not misleading, but annoying for sure.
