Watch Worlds Mission Not Working

LoL Esports
Feed your competitive spirit as we bring you the best that professional League of Legends has to offer.
I have watched a worlds VOD of SKT vs RNG game from last year (there are no worlds games for this year to watch) and have not received my reward? On your world 2018 mission post it says I can watch both a live game or a VOD to complete the mission so why did it not work?
