VS Event: I got both Garen & Darius Missions

[Gameplay] I got both the Darius and the Garen missions in the VS Event Hello,

today i logged in and instead of the usual VS page, i saw the following one: https://i.gyazo.com/40551a448e6e8f40a9391c9a44e34f6f.jpg i tried clicking on Garen (i had selected Darius before, when the event started) and after like 5 or 10 minutes i got the Garen missions too. Here's a screenshot showing me having 2 Darius and 2 Garen missions: https://i.gyazo.com/998290976bd42804cfc1c9dc49a63ed3.png .

Unfortunately, i don't really know what caused this so i can't really tell more.
