I haven't experienced that yet. I thought I had, but it turns out someone had shared one of the delve quests with me, which I hadn't completed yet. When you're hitting the board, is there any possibility you have another one of the daily quests still in your log?
I have noticed that, if I get a quest and don't complete it that day, I can complete it the next day and then go right out and hit the board again.
