Watched Worlds for mission and received rewards but no new missions are appearing

It took a while to finally get credit for watching one of the Worlds games. After completing that mission, I relogged into LoL and tried to see if any new missions are appearing. There aren't any, but we are supposed to complete 35 Worlds missions to receive an icon and emote that I really do want. I'd love to see all the mission bugs fixed soon, because I really enjoy playing League with my husband. :)
