Missions completed but not disappearing/updating

A bug with missions where missions are completed and the bar completely filling up, but they are not disappearing & rewards are not being granted. I've currently got this with "Fortune favors Fortune" and "Thrill". Screenshots here.

(By extension, because Thrill isn't being marked as complete, the "Season 2019" mission is also stuck at 6 out of 7 (Thrill should be the seventh and final one, completing Season 2019 as well.))

I believe this is the same issue being reported here and here.
