they had the original How to Train Your Dragon on demand for a bit but have moved to DVD recently

They are missing Riders of Berk and Defenders of Berk

they have Race to the Edge 6 seasons wrongly listing 2018 which is date of most recent rather than when it started

they have 1 seas of Dragon Legends which takes place after Race to the Edge and before How to Drain Your Dragon 2, even though both were released before it
