3star unit with 3 combined items mission won't complete

I had a level 3 Fiora with three combined items. I ended up winning, so I know the game completed. At the end of the game, the client never gave results, so I had to click the "skip waiting for results" button. when I went back to lobby, it said I never completed the mission that says "3star unit with 3 combined items".

It said it was still waiting for the game I just finished, so I thought maybe reclienting would help. I recliented, and the games it said it was waiting for (6 in total) all vanished, but it still didn't complete the mission for me.

sigh...
