Mecha Kingdom Quests don't progress.

Hi ! I have two Mecha Kingdom quests to complete. One is to Play a game as Draven and the other is to Receive any of the four dragons souls in Summoner's Rift. the alternate quests are to play 7 games. Now, I've received a whole bunch of dragons souls but the quest didn't get completed. Since it seemed like a bug, I decided to just play 7 games so I could complete both quests at once but it stopped progressing after 4 games despite me playing 4 of them today. As Draven is in the free rotation, I decided to see if playing a game as him would complete the quest, but it didn't, again, nor it counted toward my 7 played games. I've restarted the Client but it didn't change anything. It mostly pisses me off as the 30 tokens I'd get from the two quests would allow me to buy a Mecha Kingdom Orb before the event ends but now I won't be able to.

Is there anything that can be done ? Thanks in advance
